 According to variations of the story, the king was saved from being gored by the charging animal when it was startled either by the miraculous appearance of a holy cross descending from the skies, or by sunlight reflected from a crucifix which suddenly appeared between the hart's antlers while the king attempted to grasp them in self-defence.As an act of thanksgiving for his escape, David I founded Holyrood Abbey on the site in 1128.In the church was preserved, in a golden reliquary, an object said to be a fragment of the True Cross brought by David's mother, St. Margaret, from Waltham Abbey, and known thereafter as the Black Rood of Scotland (the Holyrood (cross)).
