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.
"[1] 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.
When Diocletian heard that she was still alive, he ordered her to be carried around the city, with weights loaded on her body.
[1] When Lucy was paraded by Geminian's house, the statues of Roman gods in his home shattered miraculously and a dove made the sign of the cross over Geminian's head.
The judge presiding at their trial was thrown from his horse on a stone bridge; his body was never found.
