Saint Lucy's Day, also called the Feast of Saint Lucy, is a Christian feast day observed on 13 December. The observance commemorates Lucia of Syracuse, an early-fourth-century virgin martyr under the Diocletianic Persecution. According to legend, she brought food and aid to Christians hiding in the Roman catacombs, wearing a candle-lit wreath on her head to light her way, leaving both hands free to carry as much food as possible.
