 Olaf was not present at the child's birth, and his Icelandic skald Sigvatr Þórðarson became his godfather.In a hasty baptism, Sigvatr named Magnus after the greatest king he knew of, also Olaf's greatest role model, "Karla Magnus", or Charlemagne.Against the odds, Magnus went on to grow strong and healthy, and he became of vital importance to Olaf as his only son.
