Regulus

Regulus, a Roman of the Romans; was twice over Consul, in 267 and 256 B.C.; defeated the Carthaginians, both by sea and land, but was at last taken prisoner; being sent, after five years' captivity, on parole to Rome with proposals of peace, dissuaded the Senate from accepting the terms, and despite the entreaties of his wife and children and friends returned to Carthage according to his promise, where he was subjected to the most excruciating tortures.
