Interesting Facts
Here are five intriguing facts about the Arch of Janus. Keep them in mind to share with friends while exploring the wonders of Rome:
- Uniqueness in Design: The Arch of Janus stands as the only surviving quadrifrons or four-faced, triumphal arch in Rome. This unique piece of architecture marked a crucial crossroads in the ancient city.
- Misunderstood Dedication: Contrary to popular belief, the Arch wasn’t actually dedicated to Janus, the Roman god of beginnings and transitions. Instead, its name derives from ‘ianua’, the Latin term for ‘door’.
- A Marker or a Market?: The Arch’s purpose still puzzles historians. While some consider it a boundary marker, others speculate that it offered shelter to traders in the Forum Boarium cattle market.
- Transformative History: The Frangipane family converted the Arch into a fortress in the Middle Ages. This adaptation allowed it to survive intact until the 19th century when its upper stage was mistakenly removed.
- An Unrestored Monument: Despite a bomb explosion in 1993 that made it inaccessible to the public, the Arch of Janus remains the last unrestored monument in the Forum Boarium, bearing a testament to its resilient history.
History of the Arch of Janus’s Construction
The Arch of Janus, nestled in Rome’s Forum Boarium, stands as an intriguing enigma in architectural history. Its four-sided, quadrifrons design is unique among Rome’s surviving ancient structures, and its origins and original purpose remain shrouded in mystery.
Its construction, estimated to have occurred in the early 4th century AD, incorporated a technique known as ‘spolia’. This practice involved reusing building materials from earlier structures, a common trait in Roman architecture. In the case of the Arch of Janus, the materials include bricks, pottery shards, and white marble slabs, likely sourced from pre-existing buildings, lending the monument a rich tapestry of history.
Despite its name, the monument is not thought to have been a traditional triumphal arch nor dedicated to the two-faced god, Janus. Its purpose has been a subject of debate among scholars. Some suggest it functioned as a boundary marker, while others propose it provided shelter for traders at the bustling Forum Boarium cattle market. There are even suggestions that it might have been dedicated to Constantine I or Constantius II.
19th-century engravings show how the Arch of Janus changed over time. In the Middle Ages, it became the base for a fortified tower. This tower was first recorded in 1145. It belonged to the Frangipane family, a powerful Roman clan. The tower is depicted in historic engravings until the early 1800s.
From 1827 to 1830, the tower and an attic were removed. They were mistakenly thought to be later additions. This change gives the Arch its current appearance. A staircase in the northwest pier suggests the original structure was larger.
The 19th-century changes aimed to make the arch look triumphal. However, this may not reflect its original design. Despite changes and mysteries, the Arch of Janus fascinates scholars and visitors. Its unique form and intriguing history testify to Rome’s layered past.
