Rabirius was an ancient Roman architect who lived during the 1st and 2nd centuries CE. [1] His designs included the massive Flavian Palace, situated on the Palatine Hill at Rome, and the Alban Villa at present-day Castel Gandolfo, both erected on a commission by his patron, emperor Domitian. [2]
It has been suggested that Rabirius designed the extant Arch of Titus, a commemorative arch located in summa Sacra Via honoring the joint triumph celebrated by Titus and Vespasian marking their successful suppression of the Jewish Revolt in 71 CE. [3]
