Superman soon had lots of company, and lots of competition! What do they have in common? All superheroes have some type of extraordinary power or ability. Their "super power" can be something they're born with: Superman, Wonder Woman, Thor. It can be the result of an accident or mutation: Spider-Man, The Incredible Hulk, Wolverine. Or, it can be simply a skill they have learned, honed and perfected beyond the average: Batman, Hawkeye. They all have a strong moral code and a motivation to rid the world of some menace.
The practice may have originated in a Celtic festival, held on 31 October–1 November, to mark the beginning of winter. It was called Samhain in Ireland, Scotland and the Isle of Man, and Calan Gaeaf in Wales, Cornwall and Brittany. The festival is believed to have pre-Christian roots. After the Christianization of Ireland in the 5th century, some of these customs may have been retained in the Christian observance of All Hallows' Eve in that region—which continued to be called Samhain/Calan Gaeaf—blending the traditions of their ancestors with Christian ones. It was seen as a liminal time, when the spirits or fairies (the Aos Sí), and the souls of the dead, could more easily come into our world. It was believed that the Aos Sí needed to be propitiated to ensure that the people and their livestock survived the winter.
