Tempio di Apollo Sosianus: "The Greek god Apollo was venerated by the Romans chiefly for his power to ward off disease (Apollo medicus). The first temple dedicated to him was raised on this site in the 5th century BC. In 34 BC Caius Sosius, governor of Cilicia and Syria, rebuilt the sanctuary in marble and it became known as the Temple of Apollo Sosianus. The three elegant fluted columns with Corinthian capitals belonged to the porch (pronaos) of the temple and were re-erected in 1940". Source: The Green Guide, Rome - Michelin Travel Publications.
