Ulpian Library

• 1. Imperial Commission And Foundation

  ›

  Emperor Trajan issued a commission in 112 AD to build a library within his new Forum. This structure rose due north of the Roman Forum at the heart of the empire. Construction finished two years later in 114 AD. The Ulpian Library became the premier scholarly center of Rome upon its completion. It served as the Public Record Office for the city with over 20,000 scrolls containing population records. Traces of storage presses were discovered during modern excavations. The non-public collection likely drew from the private library of Epaphrodites of Cheronea. That private source held more than 30,000 books and scrolls.

• 2. Archival Collections And Holdings

  ›

  Scholars estimate approximately ten thousand scrolls filled both Latin and Greek sections. These collections included archival materials like praetorian edicts and senatorial decrees. Caesar's autobiography sat alongside Trajan's commentaries on the Dacian Wars. Only a few words from those commentaries survive today. The facility housed records concerning the entire city's population. Presses stored both scrolls and bound books inside the rooms. The collection did not account for future growth in volume. Desks allowed readers to work while shelves kept books out of sight.

• 3. Architectural Design And Layout

  ›

  The building featured a two-level structure with high vaulted ceilings. Natural lighting entered through these tall spaces to illuminate the interior. A small colonnaded courtyard enclosed the Column of Trajan between the two libraries. Columns stood opposite pilasters that framed niches holding books and scrolls. Three steps led up to a walkway in front of the bookcases. Seven niches lined each wall along with four others across the back wall. Recesses at the far end held statues of Trajan and possibly Minerva. Bronze screens restricted access when the library was not in use.

• 4. Relocation And Fourth Century History

  ›

  Early in the 4th century, staff moved contents to the Baths of Diocletian. This shift may have occurred due to necessary repairs on the original site. Records show the contents were returned to the Forum at a later date. In 455 AD Emperor Avitus ordered a bust of Didonius Appollinarius there. This specific order marks one of the final known administrative actions within the facility. The move disrupted normal operations but did not destroy the collection entirely. Staff managed the transition during a period of political instability.

• 5. Survival Until The Fall Of Rome

  ›

  This library remained operational until the mid-fifth century while other ancient libraries perished earlier. It is the only Roman library known to have survived until the Fall of Rome. Its longevity continued even after the destruction of the Library of Alexandria in the 3rd century. The Ulpian Library became a major library in the Western World following that loss. Other facilities closed or burned before reaching this late date. The structure endured through centuries of changing emperors and shifting priorities.

• 6. Modern Reconstructions And Excavations

  ›

  Digital reconstructions show the view from inside the west Greek library. These models look through bronze screens into the portico where the base of the Column of Trajan stands visible. Portions of the floor and podium of one wall survive today. Archaeologists used these fragments to build physical models of the interior. The digital reconstruction displays how light entered the space each morning. Vitruvius recommended libraries face east to capture that early sunlight. The surviving podium allows researchers to verify the original layout plans.
