St Elmo's Day- 2nd June

According to legend St Elmo or Erasmus of Formia who was martyred by having his intestines drawn from his body by a windlass. So his name is now invoked against all stomach and bowel complaints. He is also the patron saint of sailors, because he is said to have continued preaching even after a thunderbolt struck the ground beside him, this prompted the sailors who witnessed this event and who were also in danger from sudden storms and lightening to claim his protection. 

St Elmo's Fire, a bright blue or violet glow, the electrical discharge that flickers ships during storms is believed to be a sign of his protection.
