The Temple of Piety was a Roman temple dedicated to the goddess Pietas, a deified personification of piety. It was erected in 181 BC at the northern end of the Forum Olitorium, the Roman vegetable market, and demolished in 44 BC to make room for the building eventually known as the Theater of Marcellus. It seems to have been rebuilt and its services continued well into the imperial period, although this is disputed by some scholars.

Manius Acilius Glabrio was a plebeian Roman politician and general during the Republican. He served as consul in 191 BC while Rome was at war with the Seleucid Empire. He defeated Emperor Antiochus the Great at Thermopylae, helping establish Roman unipolar control over the Mediterranean, and was awarded a triumph. Credible accusations that he had embezzled spoils from his conquests in Greece while consul caused him to withdraw from his attempt to run for censor, after which he largely retired from public life.
