In 312 BC,
Appius Claudius Caecus, during his
censorship, attempted to persuade the Potitii and the Pinarii to instruct the public slaves in these rites. The Pinarii refused, but the Potitii accepted Claudius' offer of 50,000 pounds of copper.
Niebuhr explains that Claudius' intention was to introduce the worship of Hercules, formerly
sacra privata, into the religion of the
Roman state, thus making them
sacra publica. However, because no
flamen could be appointed for a foreign god, it was necessary to entrust the rites to slaves. For their impiety, Hercules sent a plague that carried off the entire gens in the span of thirty days; twelve families and thirty grown men perished, and Claudius himself was struck blind, which is how he obtained his
cognomen. There is some uncertainty as to the chronology of this legend; Claudius could hardly have been blinded during his censorship, as he went on to be
consul in 307, and again in 296 BC, and was then nominated
dictator in 292 and 285. Niebuhr suggests that the Potitii may instead have died in a terrible plague that struck Rome in 292. ==In popular culture==
