St., or ST MUNGO, a famous saint of the Popish church, who flourished in Scotland in the fifth century, said to have been of the royal blood of both Scots and Picts, being the son of Thametis, the daughter of Loth king of the Picts, by Eugene III., king of Scotland. The bishoprics of Glaigow and St Aflaph were founded by him in 560. He obtained the appellation of Mungo from the affection of his tutor St Serf or Servanus, bishop of Orkney, who called him Mongah, which in the Norwegian language, signifies dear friend.
