The Feast of St. Barbara, Virgin and Martyr
is today. There is information on her here. G.K. Chesterton wrote a bit of verse about her. She is one of the Fourteen Holy Helpers. It is also the feast of St. Giovanni Calabria, Priest and Founder, pen pal of C.S. Lewis. (They corresponded in Latin.)

In the Eastern Church, this is the feast of St. John Damascene, Priest and Doctor of the Church.
