Description

Antoninus Pius (Titus Aelius Hadrianus Antoninus Augustus Pius), also known as Antoninus, was Roman emperor from 138 to 161. He was one of the Five Good Emperors in the Nerva–Antonine dynasty and the Aurelii.

His reign is notable for the peaceful state of the Empire, with no major revolts or military incursions during this time, and for his governing without ever leaving Italy. A successful military campaign in southern Scotland early in his reign resulted in the construction of the Antonine Wall. Antoninus was an effective administrator, leaving his successors a large surplus in the treasury, expanding free access to drinking water throughout the Empire, encouraging legal conformity, and facilitating the enfranchisement of freed slaves.

The as (plural asses), also assarius (rendered into Greek as ἀσσάριον, assarion) was a bronze, and later copper, coin used during the Roman Republic and Roman Empire.
