Apollodorus of Damascus (Ancient Greek: Ἀπολλόδωρος ὁ Δαμασκηνός) was an architect and engineer from Roman Syria, who flourished during the 2nd century AD. As an architect he authored several technical treatises, and his massive architectural output gained him immense popularity during his time. He is one of the few architects whose name survives from antiquity, and is credited with introducing several Eastern innovations to the Roman Imperial style, such as making the dome a standard. He is also known as Apollodorus Mechanicus.General info from Wikipedia.org
