Traian's sestertius

The sestertius coin represents the bust of emperor Traian (98 - 117 ad). During his reign
both the aqueduct Aqua Traiana and the Baths of Traian were put into use. The Aqua Traiana was built
in the years 109 - 117 AD. This specimen was coined between 103 - 112 ad. The image on the reverse
can be interpreted in different ways: the genius of the aqueduct, an image of a castellum aquae (water
distribution station) at the end of this Roman aqueduct, or a collection of general elements of the water
supply of Rome. See details under wds3
