Key information:

The Forum of Trajan is the last and the largest of the imperial fora.  The land was cleared already by Domitian, who was obviously preparing to build a large structure, if not his own forum.  A large staircase and the nymphaeum wall that abuts the firewall of the Forum of Augustus (beneath the loggia of the House of the Knights of Malta)  are dated to the reign of Domitian, so it seems that he had, indeed, begun clearing the area, ostensibly removing the large tuff ridge that previously joined the Quirinal Hill to the Capitoline Hill. 

The Forum of Trajan was dedicated in January 112.  Apollodorus of Damascus was the architect (Dio History, 69.4.1). It was a masterpiece of marble and gilded bronze that was one of Rome’s most splendid architectural creations, as noted by Constantius II during his sole visit to Rome in 357 (Ammianus History, 16.10.15-16).

The site was composed of a massive piazza (itself 110 X 85 meters) with a huge equestrian statue of Trajan, the Basilica Ulpia (600 feet long with a gilded bronze roof and behind it the Column of Trajan narrating the Dacian Wars with 2500 carved figures to a height of 45 m (with colossal statue of Trajan on top),  flanked by Greek and Latin libraries, comprising over 240 meters X 175 meters. The piazza, lined with marble pavers, was surrounded by porticoes that hid exedrae, as per the Forum of Augustus. Along the Quirinal Hill slopes there was the massive brick complex on three levels that excavators called the Markets of Trajan, though it is not known if the site was for shops or administration, or both. 

There is a small shrine on the side facing the Forum of Augustus, followed by a monumental triple arch entrance, revealed in the 1990s excavations. 

There is some debate as to the existence or location of the Temple of Trajan, which most scholars locate somewhere between the Churches of S. Maria in Loreto and Santissimo nome di Maria.  

The site’s pavement of marble was removed by the 9C, followed by a massive dump of ancient material to raise the ground level.  A neighborhood developed, with plots of land for agriculture. A neighborhood with homes and streets took shape by the 13C with subsequent modifications and the addition of a hospital, tied to the Knights of S. John, who also occupied part of the firewall of the Forum of Augustus.  These findings were revealed through the excavations of the 1990s of some of the garden areas planted during the initial presentation of the Vie dei Fori Imperiali in the Fascist era; many of the medieval walls are still visible, build directly onto the Trajanic pavement. Currently, a section of the Via Alessandrina from the papal neighborhood that divides the Markets area from the forum piazza, is being excavated.

From Platner & Ashby’s (1929) Topographical Dictionary of Ancient Rome:

FORUM TRAIANI, (sometimes Ulpium: Hist. Aug. Marc. 22. 7; Sid. Apoll. Carm. 2.544; CIL vi. 1724, 1749): the last, largest and most magnificent of the imperial fora, built by Trajan with the assistance of the Greek architect Apollodorus, and dedicated, at least in part, about 113 A.D. (Cass. Dio lxviii. 16. 3; lxix. 4. I; Vict. Caes. 13. 5:adhuc Romae a Domitiano coepta forum atque alia multa plusquam magnificecoluit ornavitque, which may perhaps mean that the work was planned and possibly begun by Domitian; see S. Sculpt. 149; ScR 135; NS 1907, 415; CQ 1908, 144). When completed by Trajan it consisted of the forum proper, the basilica Ulpia, the column of Trajan, and the bibliotheca, and extended from the forum Augustum north-west between the Capitoline and Ouirinal hills, with the same orientation as the other imperial fora. Unlike these it did not contain a central temple of which it formed a virtual porticus (for the possible significance of the sacellum Libertatis, see below). After Trajan’s death, however, Hadrian erected the great temple of Trajan on the north-west side of the bibliotheca (Hist. Aug. Hadr. 19. 9; CIL vi. 966, 31215), which thenceforth formed an integral part of the forum whole, and made it conform somewhat to the imperial type. Although the walls of the forum of Trajan and the forum of Augustus seem to have been separated by a short distance, they must have been connected by a wide avenue at least, and thus Caesar’s plan of connecting the forum Romanum and the campus Martius (Cic. ad Att. iv. 16. 8) was finally carried out.

The construction of Trajan’s forum necessitated much excavation and levelling. The space thus prepared was 185 metres in width, and the extreme length of forum and temple precinct was about 310 metres. The inscription on the pedestal of the column (CIL vi. 960: senatus populusque Romanus imp. Caesari divi Nervae f. Nervae Traiano… ad declarandum quantae altitudinismons et locus tan<tis oper>ibus sit egestus) in connection with a passage in Cassius Dio (lxviii. 16. 3:ἔστησεν…κίονα μέγιστον ἅμα μὲν ἐς ταφὴνἑαυτῷ ἅμα δὲ ἐς ἐπίδειξιν τοῦ κατὰ τὴν ἀγορὰν ἔργου παντὸς γὰρτοῦ χωρίου ἐκείνου ὀρεινοῦ ὄντος κατέσκαψε τοσοῦτον ὅσον ὁ κίωνἀνίσχει καὶ τὴν ἀγορὰν ἐκ τούτου πεδινὴν κατεσκεύασε) was formerly taken to mean that the height of the column (100 Roman feet) was that of a ridge between the Capitoline and Quirinal hills which had to be cut away, but geological evidence showed that it never existed. This was confirmed by the discovery of an ancient street and houses of the early empire beneath the foundation of the column (NS 1907, 389-410, 414-427; CQ 1908, 141-144). In view of this fact various attempts have been made to explain the inscription, and especially mons, in some other way (Boni, NA 1906, I Nov.; Proceedings of the British Academy iii. 1907,93-98; Binder, Die Plebs, Leipzig 1909, 42-5 ; Comparetti, RL 1906, 570-588; Mau, Mitt. 1907, 187-197; Richter, Internationale Wochenschrift 1907, 664-668; Sogliano, Atti dell’ Acc. d. Napoli xxiv. 1908, 79-98; Nazari, Atti dell’ Acc. di Torino xliii. 1908, 595-613; Rasi, Atti dell’ Acc. di Padova, 1910, 167-176; Rasi, Riv. di Fil. 1910, 56-62; Graffunder, BPW 1912, 1736; Ramorino, Giornale d’ltalia, Rome 1906, Nos. 308, 310, 318; La Nazione, 7 Nov. 1907. Cf. the summary by Nazari (loc. cit. 595) ‘ Veramente questo studio dovrebbe piuttosto intitolarsi le peripezie di un monte che si credette esistito fino a questi ultima tempi, fu negato dal Boni il quale gli sostituisce il vicino Quirinale, fu idealmente recostituito dal Comparetti con marmi fatti venire dall’ Egitto dalla Libia e da altri lontani e vicini paesi, divenne per opera del Ramorino una montagna di capolavori artistici, fu inalzato dal Sogliano scaricando immondizie e detriti portati poi via da Traiano, e finalmente fu ridotto ad un bastione dal Mau ‘). The least unsatisfactory explanation as yet suggested is that mons refers to the extreme eastern shoulder of the Quirinal, the collis Latiaris, that was cut back so far that the height of the excavation was approximately 100 feet (Hulsen, Geogr. Jahrbuch xxxiv. (1911), 203-205). Groh (RL 1925, 40-57) accepts this view, explaining that the mons was probably situated to the north-west of the forum of Augustus; and suggests that the column was not placed there, but further west, in order that Trajan’s tomb might not fall within the Pomerium.

The forum proper was a rectangular court (Gell. xiii. 25. 2: in area fori) 116 metres wide and 95 long (according to LF 22, who places the south-east wall of the forum 25 metres farther from the forum Augustum than other topographers), enclosed by a wall of peperino faced with marble, except on the sides, where great hemicycles, 45 metres in depth, projected outwards. Around three sides was a colonnade of different kinds of marble, single on the south-east, and double on the north-east and south-west. The entrance to the area was in the middle of the south-east side, opposite the forum of Augustus, where in 116, the year of Trajan’s death, the senate erected a magnificent arch to commemorate his victories in Dacia (Cass. Dio lxviii. 29). This arch is represented on coins (Cohen, Traj. 167, 169) as single, but with three columns on each side of the passage way and niches between the columns. It was surmounted by a six-horse chariot, in which stood the emperor crowned by Victory (Baumeister, Denkmaler, fig. 1974). On the roof of the colonnade were gilded statues of horses and military standards, provided from the spoils of war (Gell. xiii. 25), and in the centre of the area was a bronze equestrian statue of Trajan himself (Amm. Marcell. xvi. 10. 15: in atrio medio; Cohen, Traj. 1, 2). On each side was a smaller arch; and the three entrances corresponded to those of the basilica Ulpia. One of the colonnades in this forum was called porticus Purpuretica, probably because the columns were of porphyry (Hist. Aug. Prob. 2; (but cf. SHA 1916, 7. A, 9; 1918, 13. A, 46, where this statement is called a pure invention); CIL xv. 7191; BCr 1874, 50).

In the intercolumnar spaces of the porticoes, and perhaps here and there in the area, Trajan and his successors set up statues of many distinguished statesmen and generals (Hist. Aug. Marci 22. 7; Alex. Sev. 26. 4: statuas summorum virorum in foro Traiani conlocavit undique translatas; Sid. Apoll. Carm. 9. 301 and CILvi. 1724, Merobaudes; Sid. Apoll. Carm. 8. 8 and Ep. ix. 16. 25-28, Sidonius himself; Hier. Chron. p. 195 (Sch.) and Aug. Conf. viii. 2. (3), Victorinus; Hist. Aug. Tac. 9. 2, the Emperor Aurelian). A large number of the inscriptions on these statues have been found within the precincts of the forum, some of which state that they were placed ‘in foro Traiani ‘ (M. Claudius Fronto, CIL vi. 31640, M. Bassaeus Rufus 1599, Claudian the poet 1710, Flavius Eugenius 1721, Fl. Peregrinus Saturninus 1727), in foro Ulpio (Merobaudes 1724, Petronius Maximus 1749), while the rest omit any such statement (CIL vi. 959, 967, 996, 1497, 1540,1 1549, 1566, 1653, 1683, 1725, 1729, 1736, 1764, 1783, 1789, 3559=32989, and probably also 997).

In this forum the consuls, and presumably other officials, held court (Gell. xiii. 25. 2), and slaves were freed (Sid. Apoll. Carm. 2. 544-545); here Hadrian burned the notes of debtors to the state (Hist. Aug. Hadr. 7. 6), Marcus Aurelius sold the treasures of the imperial palace to defray the expenses of war (Hist. Aug. Marc. 17. 4; 21. 9; Eutrop. viii. 13; ep. de Caes. 16. 9), and Aurelian burned the lists of the proscribed (Hist. Aug. Aurel. 39. 3; cf. Cass. Dio lxxi. 32. 2); and here the laws were frequently fastened up on bronze tablets (cf. cod. Theodos. xiv. 2. 1: proposita in foro Traiani; Leges Novellae Valentiniani III, ed. Meyer- Mommsen 19.4; 21. . 7; 2. 6; 23. 9; 27. 8; 31 7. et passim). Down to 353 A.D. the senators kept their money and silver in chests in this forum and the place of deposit was called Opes (Schol. Iuv. 10. 24). The forum is represented on coins (Cohen, Traj. 167-169), and is mentioned in Reg. (Reg. VIII, app.; Pol. Silv. 545).

The hemicycle on the north-east side of the forum area has been partially excavated (NS 1907, 414-427). Built of ornamental brick with travertine trimmings, it consists principally of two stories of chambers abutting directly against the side of the Quirinal hill (II. 30). The rooms on the ground floor, which were probably shops, open on the marble pavement2 of the forum. Above the first story is a gallery with Tuscan pilasters, into which the rooms of the second story open. Above this gallery there was another story, the front of which was not flush with the lower facade but pushed back on the slope of the hill. The semi-circular space in front of this hemicycle was paved with white marble and surrounded with a colonnade decorated with gilt bronze trophies.

Still higher, on the upper level of the Quirinal, is a series of halls, now occupied by the barracks of the Milizia, approached by steps from the forum level (Ann. Assoc. Art. cult. Arch. 1910-11 (Rome 1912), 43). The mediaeval name Magnanapoli is by some thought to be a corruption of Balnea Pauli, but this is itself merely a sixteenth century invention, based on a false reading in Juvenal vii. 233. (See BALINEUM PHOEBI.) Cf. Adinolfi, Roma nell’ eta di mezzo, ii. 43, 47.

Hulsen quotes a privilege of 938 (Reg. Subl. p. 63, n. 24) which speaks of Adrianus quondam de banneo Neapolim3; and the name occurs in the form mons Balnei Neapolis and mons Manianapoli in the thirteenth century (HCh 351). Here must have been situated the church of S. Salvator de Divitiis or in Cryptis (HCh 438).

Two drawings by Cronaca (?) show a portion of the south enclosure wall of the forum proper, which was of blocks of white marble, and decorated with an internal colonnade like the forum Transitorium, with a line of tabernae outside. The frieze with a griffin and cupids, now in the Lateran (SScR 150, pl. 33), belonged to this wall (Bartoli, in Mem. AP I. ii. 177-192), and from its style has been attributed to the period of Domitian. It has also been thought that the brickfacing of the north-east hemicycle is characteristic of his reign (RA 113). If, however, this were so, we should have to attribute to Domitian the removal of the mass of earth from the slopes of the Quirinal which is communicated by the inscription on the column of Trajan-and this is of course impossible.

The name porticus curva (Cassiod. Var. iv. 30) should probably be applied to the south-western hemicycle of this forum, and not to the apse of the Secretarium Senatus; see CURIA IULIA (p. 146).

On the north-west side of the area of the forum was the basilica Ulpia (probably completed in 112 A.D., CIL vi. 959; FUR frgs. 25-26; Not. app.; Cohen, Traj. 42-44; Hist. Aug. Com. 2. I : in basilica Traiani; Geog. min. ed. Riese, p. 120: sicutet quae dicitur forum Traianum quae habet basilicam praecipuam etnominatam), rectangular in shape with apses at each end. Its floor was one metre higher than the level of the area, and was approached by flights of steps of giallo antico. The main entrance was in the middle of the east side, from the area of the forum, where there was a decorative fagade, represented with variations on three coins (Cohen, Traj. 42-44). This consisted of a row of ten columns, probably of yellow marble, in the line of the wall, with six others in front on three projecting platforms. These columns supported an entablature and attics on which stood quadrigae and statues of triumphatores. The central quadriga was escorted by Victories. The great hall of the basilica was surrounded with a double row of columns, 96 in all, probably of white or yellow marble, with Corinthian capitals, which formed two aisles 5 metres wide, and supported a gallery on both sides of the nave and at the ends. The nave itself was 25 metres wide, and the total length of the rectangle, without the apses, about 130. The walls of the basilica were faced with marble, and its roof was of timber covered with bronze which is mentioned by Pausanias (v. 12. 6; x. 5. II) as one of the most notable features of the whole structure.

The central part of the basilica has been excavated, but the fragmentary granite columns now standing do not belong here, although they have been placed on the original bases. Some of the original pavement of white marble is still in situ (Lesueur, La Basilica Ulpienne, restauration executee en 1823, Paris 1878; cf. D’Esp. Fr. i. 78). The architectural fragments now visible in the forum have not been properly assigned to its various parts (Toeb. i. 62-66). For the reliefs attributable to the frieze which decorated the wall surrounding the forum, some of which were used for the decoration of the arch of Constantine, while other fragments are in the Villa Medici and the Louvre, see PBS iii. 225; iv. 229-258; SScR 142-150 (and esp. 135, 151 n. 17, where it is suggested that the whole series may illustrate Domitian’s Dacian campaigns) 418; Mon. Piot, 1910, xvii. 206-239; Sieveking in Festschr. f. P. Arndt, 29, who attributes them to Hadrian, and in Mitt. 1925, 161-166, where the fragment at Cannes is described.

On one of the fragments of the Marble Plan (FUR frg. 25; pp. 28, 31; Jord. i. 2. 460), in the north-east apse of the basilica, is the inscription LIBERTATIS; and Sidonius Apollinaris (Carm. ii. 544, 545: nam modo nos iam festa vocant et adUlpia poscunt/Te fora donabis quos libertate Quirites) seems to refer to this shrine, and to indicate that the ceremony of manumitting slaves, previously performed in the ATRIUM LIBERTATIS (q.v.), took place here. This was probably a sacellum, not merely a statue, and its presence may indicate that this goddess was recognised as the presiding divinity of this forum, a choice significant of the liberal character of the emperor.

On the north-east side of the basilica Ulpia was a small rectangular court, 24 metres wide and 16 deep, formed by the basilica itself, the two halls of the bibliotheca (see below), and, later, the temple of Trajan. In the centre of this court the columna Traiani was erected in 113 A.D. Nibby (Roma Antica ii. 183) had already pointed out that the colonnade joining the two libraries on the north was only removed when the column was built (Toeb. i. 62).

Its construction is ascribed in the dedicatory inscription on the pedestal to the senate and people (CIL vi. 960: senatus populusque Romanus imp. Caesari diviNervae f. Nervae Traiano ad declarandum quantum altitudinis mons et locustan<tis oper>ibus sit egestus), but elsewhere to Trajan himself (Cass. Dio lxviii. 16), who is said to have built it to show the depth of excavation of his forum, and for his sepulchre.4 It is also figured on several coins of Trajan after 113 (Cohen, Traian 115, 284, 359, 555-6).5 It was called columna cochlis (Not. Reg. VIIi), and was a columna centenaria, like the COLUMN OF M. AURELIUS(q.v.), although the latter adjective is not actually applied to it in the few extant references in ancient literature.

It is built of Parian marble. The shaft and basis, composed of 18 blocks, 3.70 metres in diameter, with the additional block that forms the capital, and the plinth which is cut in the upper block of the pedestal, measure 100 Roman feet (29.77 metres) in height. The height of shaft and pedestal together is 38 metres, which corresponds with the figures of the Notitia (columnam cochlidem altampedes cxxviii semis (Cur.: cxxviis) ). On its top was a statue of Trajan in gilt bronze, of which we have no representation. Sixtus V erected the present statue of S. Peter in 1588.

Within the hollow column a spiral staircase with 185 steps leads to the top (so also Not.: gradus intus habet clxxxv-Cur.: CLXXX). Light is furnished by 43 narrow slits in the wall (Not.: fenestras XLV). The pedestal, 5.4 metres high and 5.5 square, is ornamented on three sides with trophies. The south-east side has a door, and above it the inscrip- tion. Within the pedestal are a vestibule, a hallway, and a rectangular sepulchral chamber lighted by a window on the south-west side, in which the ashes of Trajan in a golden urn were probably placed (Eutrop. 8. 5; Cass. Dio lxix. 2; Aur. Vict. ep. 13; Hier. ad a. Abr. 2132; Cassiod. Chron. 141). This chamber was evidently robbed, for when re-excavated in 1906 (NS 1907, 361-401; CR 1906, 379; Builder xc. 1906, 368), it was found that a hole had been cut through the travertine foundation. To secure the stability of the structure the chamber itself had afterward been filled up with concrete, certainly after 1764, in which year one Radet wrote his name on the lintel of the door (CR cit.).

The entire surface of the shaft is covered with reliefs, arranged on a spiral band, which varies in width from about go centimetres at the bottom to nearly 1.25 metre at the top. These reliefs represent the principal events in the campaigns of Trajan in Dacia between 101 and 106 A.D., and also form a complete encyclopedia of the organisation and equipment of the Roman army in the second century. The average height of the figures is 60 centimetres, and they were cut after the column had been erected, so that the joints of the blocks are almost entirely concealed. These reliefs were also coloured most brilliantly (Bull. d. Inst. 1833, 92; 1836, 39-41).6 Casts of these reliefs may be seen in the Lateran Museum, St. Germain near Paris, and the Victoria and Albert Museum, South Kensington, London (for these reliefs, see Frdhner, La Colonne Trajane, Paris 1874; Percier, Restauration des monuments antiques pt. ii. 1878 ; Cichorius, Die Reliefs der Trajans-Saule, 2 pts. Berlin 1896; Petersen, Trajans Dakische Kriege 1903; D’Esp. Mon. ii. Iio;  Fr. i. 79-81 ; S. Sculpt. 166-213; CR 1906, 235; PBS v. 435-459; vi. 177– 185; JRS 1917, 74-97; SScR 153-190; Lehmann-Hartleben, Traians- Saule, Berlin 1926: for the development of the theory that the form of the monument was suggested by the papyrus roll and that the reliefs were designed to be monumental illustrations of the history of his campaigns that Trajan himself (cf. Priscian. apud. Keil. ii. 205. 6) wrote, see Birt, Die Buchrolle in der antiken Kunst, Leipzig 1907, 269-315; RhM 1908, 39-57). In this connection it is worth noting that the earliest exemplification of the idea of a column decorated with a spiral band may be seen in a fresco on the back wall of the central room (the so-called tablinum) of the house of Augustus (Livia) on the Palatine (Mon. Inst. xi. 22).

The little church of S. Nicolas de Columna at the base of the column is mentioned as early as 1029-32 (HCh 394-396). It disappeared between 1560 and 1570. For some heads of animals which may have come from the forum, see LS ii. 127; PT 178; and for the relief of an eagle in the church of SS. Apostoli, which is traditionally attributed to this forum, see MD 3539; SScR 206.

On either side of the column and abutting against the north-east wall of the basilica were the two buildings of the library, the bibliotheca Ulpia (Hist. Aug. Aur. 8, 24); also called bibliotheca templi Traiani (Gell. xi. 17; cf. CIL vi. 9446: atria Traiani;7 Cass. Dio lxviii. 16: κατεσκεῦασε δὲ (Trajan)καὶ βιβλίωνἀποθήκας). One building was for Greek and the other for Latin books. In both were reading rooms, and on the walls were placed busts of celebrated authors (Sid. Apoll. ix. 16. 27). State archives, such as the edicts of the praetors and the libri lintei, or acts of the emperors, were kept here (Hist. Aug. Aur. I ; Tac. 8; Numer. II). At a later period, and for some unknown reason, the books were transferred to the baths of Diocletian (Hist. Aug. Prob. 2; see Boyd, 17-19, 37-39). v. Domaszewski (SHA 1916, 7 A, 9; 1918, 13 A, 49-52) considers all the statements of the author of the Hist. Aug. to be pure inventions, arguing that the only correct name for the library is bibliotheca Traiani, and that the bibliotheca Ulpia was a library in Nemausus (Nimes) of which the author was curator. See SCHOLA FORI TRAIANI.

The forum of Trajan was completed by Hadrian, who erected the great temple of Trajan and his wife Plotina, templum divi Traiani (Not. Reg. VIII; Gell. xi. 17. I; Hist. Aug. Hadr. 19. 9: numquam ipse nisi in Traiani patris templo nomensuum scripsit-an inaccurate statement, cf. AJA 1905, 441-449, or rather a pure invention (v. Domaszewski, cit. 1918, 13 A, 46). Fragments of the double dedicatory inscription (CIL vi. 966=31215) have been found. The temple was octostyle peripteral, and stood on a raised platform, round which was a porticus. Fragments of its granite columns 2 metres in diameter, of smaller columns 1.80 metre in diameter, and some corresponding capitals of the Corinthian order, have been found at various times (Bull. d. Inst. 1869, 237; NS 1886, 158 ff.; for possible remains of pavement of the colonnade, see NS 1904, 153-157; BC 1904, 341-346; and for a base which may have belonged to it, JRS 1919, 192). The reliefs (supra, 241) found within the area of the forum may have belonged to the temple, but more probably to the encircling colonnade.

The forum of Trajan was probably the most impressive and magnificent group of buildings in Rome (Cassiod. Var. vii. 6; Vict. Caes. 13. 5; Paus. locc. citt.), and a vivid picture is given of the astonishment of the Emperor Constantius on the occasion of his visit to it in 356 A.D. (Amm. Marcell. xvi. 10. 15). The history of its destruction begins with the sixth century, and throughout the Middle Ages it furnished an almost inexhaustible supply of decorative material for the churches and palaces of Rome (cf. BC 1901, 300-308; DAP 2. xv. 367-368; LS passim).

See Jord. i. 2.453-467; Gilb. iii. 234-237; LR 312-321; DuP 117-119; ZA 44-52; RA 113-116. For restorations, see Richter e Grifi, Ristauro del Foro Traiano, Rome 1839; Canina, Edifizi ii. pls. 111-125; D’Esp. Mon. ii. 103-109; Fr. i. 76, 77, 80; cf. also Mem.L. 5. xvii. 523, 524; ASA 54-57, 84, 122.

1 This inscription, set up in honour of Vitrasius Pollio, mentions one statue set up in the Forum of Trajan, and one in the pronaos of the temple of Antoninus and Faustina (?). See CII vi. 31676. 1566 has in foro Divi (Traiani).

2 This was afterwards covered by a mediaeval road (Gnomon iii. 6o).

3 This, as Hulsen has suggested, may be a mistake for Neapolini, the name of the owner of the bath.

4 Lehmann-Hartleben (Traianssaule, 3-7) maintains (a) that a further examination of the chamber in the base shows that a marble table was fixed there to carry the urn, (b) that there is no room for the letters SOPER but only for sop, so that tan(tis opi>bus should be read. ‘ Rupibus ‘ is proposed in Rev. Ot. anc. 1922, 303-305, but seems to him as unsatisfactory as other previous suggestions.

5 As Lehmann-Hartleben points out, the earlier coins (Cohen, ib. 357, which is earlier than iio; in ib. 358 the type survived till 115) show a bird, probably an eagle, on the top of the column, which, when first projected, was not intended to serve as Trajan’s tomb, though the change of object had come before its erection had actually begun.

6 So PI. 289: but both statements are open to question.
