Key information:

Arches are a core feature of Roman architecture, from forming part of monumental structures such as amphitheaters  and aqueducts to developing a role in the quintessential triumphs of victorious generals and emperors. Many later Republican and Imperial arches flanked the route of the triumphal procession. The three triumphal arches that remain standing in Rome have central positions: the Arch of Constantine next to the Colosseum, the Arch of Titus on the Via Sacra, and the arch of Septimius Severus in the Roman Forum. The Via Appia was also a common place for monumental constructions, including some examples of memorial arches. Close to Porta Appia lies the so-called Arch of Drusus, which is dated to the early third century CE and so is likely unrelated to the eponymous stepson of Augustus.

The Arch of Drusus was constructed to embellish the aqueduct supplying water to the Baths of Caracalla at the point where it crosses Via Appia. It is composed of two columns topped by an architrave and pediment. Although today it once again stands alone, during the fifth century CE it was incorporated into the defensive Honorian Wall. The original dedication and patron of this arch is not known, but at some point after its construction, it was mistaken for the Arch of Drusus which presumably had already been lost by that time.

Drusus was born in 38 BCE to Livia shortly after her remarriage to Octavian (later Augustus); consequently, there is speculation whether his father was her first husband or Augustus. Octavian adopted his stepson in 32 BCE, and he grew into a proficient military commander, responsible for the conquest of Germania in 12 BCE for which he was awarded with a triumph the following year. He died in 9 BCE, cutting his military and political career short. His elder brother Tiberius had also been adopted by Octavian and became the second emperor of Rome. Through his marriage to Antonia Minor, the daughter of Mark Antony and Octavian’s sister, Octavia, Drusus was the direct ancestor of three emperors: his son, Claudius, his grandson, Caligula and his great-grandson, Nero, the last Julio-Claudian emperor.

The true Arch of Drusus is known to have been constructed over two centuries prior to the current Arch of Drusus, also along Via Appia, likely soon after his death in 9 BCE. It is recorded as a marble structure decorated with trophies, and its location is believed to have been close to the junction between Via Appia and Via Latina. During roadworks in the 1930s, foundations of an arch dating to the relevant period were unearthed and linked to the Arch of Drusus; they lie midway between the presetn-day Arch of Drusus and Porta Appia. Two other arches recorded along Via Appia honoring the deified Trajan and Lucius Verus are thought to have stood near a temple to the god Mars, although the locations of these monuments have not yet been identified. Nevertheless, the name of Drusus survives in the misattributed arch, and the Roman tradition of triumphal and memorial arches has continued into modernity, a prominent example being the 50-meter Arc de Triomphe in Paris, France.

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

Arcus Drusi:  erected by the senate some time after 9 B.C. in honour of the elder Drusus.

It was of marble, adorned with trophies, and stood on the via Appia, probably a little north of its junction with the via Latina. It seems to have given its name to the Vicus Drusianus and is probably the arcus Recordationis of the Einsiedeln Itinerary (11.3; 13.24; cf. Mon. L. I.515; DAP 2.ix.416).
