Swithun (or Swithin, Old English: Swīþhūn; died c. 862) was an Anglo-Saxon bishop of Winchester and subsequently patron saint of Winchester Cathedral. His historical importance as bishop is overshadowed by his reputation for posthumous miracle-working. According to tradition, the weather on his feast day (15 July) will continue for forty days. The precise meaning and origin of St Swithin's name is unknown, but it is largely considered to mean 'Pig Man'.
