@mawr also not a god but a saint; St. Guy of Anderlecht was a humble farmer, whose teams would plough fields for him while he snuck off to get in some extra praying. Medieval sainthood worked on kinda tenuous connections so that makes him the patron saint of draft horses and those who work with them, which is how I know about this, researching what saint might be revered by my Ironclaw character.
@Leucrotta I should have suspected you would have a book ready to write on this subject :D
