Saint Mungo, also known as Saint Kentigern, is the patron saint of Glasgow, Scotland. He is believed to have lived in the 6th century and is credited with founding the city of Glasgow. His life is marked by various miracles, including the revival of a dead bird, which is symbolically represented in the city's coat of arms. Mungo's feast day is celebrated on January 13th. He is often depicted with four symbols representing his miracles: a bird, a bell, a tree, and a fish. These symbols reflect his role as a missionary and his dedication to spreading Christianity in Scotland.
