Who they were

Lucy and Geminian were venerated on 16 September as saints who died as martyrs in Rome during the persecution of Diocletian in about 290 or 300 or, more precisely, in 304. Veneration for them was ancient but their story is "only known from fabulous acts." Lucy appears to be in reality the same as the Lucy of Syracuse whose feast is on 13 December, but the Geminian who was venerated on 16 September seems to be a fictitious character, not to be confused with Geminianus, Bishop of Modena.
