The story of Saint Patrick’s Day is really a story about stories themselves, how they change and evolve, and how one story or figure can become something different for different generations and eras. Today we mark St. Patrick’s Day as a celebration of Irish history and heritage, and yes, for a lot of folks that just means an excuse to have a drink or two (please, go with Guinness and not disgusting green beer) and wear a fun hat, but the real history of Saint Patrick and the evolution of the holiday is a fascinating tale.
