What was Lucy's occupation?

Answer 1

One could simply answer martyr. Saint Lucy lived from 283 to 304 A.D. She had no occupation, she rejected her arranged marriage to a pagan, asking that her dowry be spent on alms to the poor, for the glory of God. She was tortured, but even after being stabbed through the throat, she prophesied against her persecutors; then her eyes were gouged out, but she was reported as being still able to see. Nonetheless, these wounds resulted in a slow, painful death.
Lucy was a young Christian lady in Syracuse, Sicily, who had vowed he life to the service of the Lord and this led her to be martyred. If she had any specific occupation beyond serving God, we are unaware of it.
