Today is Saint Casimir's day. Casimir was the son of the King of Poland who had been sent to Hungary at the Hungarianss request for a king. Casimir didn't fulfill the plan and returned home. He refused to marry the emperor's daughter because he had decided to live a celibate life. He was King of Poland for a time and Grand Duke of Lithuania.
Unrelated to the saint, except for a commonality in name, is the Sufjan Stevens song "Casimir Polaski Day" one of my favorite songs and probably the best song ever written by Sufjan Stevens. If you know the song, give me a witness. If you haven't heard it, check it out: Sufjan Steven's "Casimir Polaski Day".
