Relating to the writing of the lives of saints or religious figures, often in a way that idealizes them.
The book was a hagiographical account of the saint's life, highlighting his miracles and virtues.
Hagiographical → It is formed from "hagio-" (from Greek "hagios", meaning holy or sacred) and "graphia" (from Greek "grapho", meaning to write). The word refers to writing about the lives of holy or sacred figures, particularly saints.
Think of 'holy' ('hagio-') and 'writing' ('graphia') to remember that hagiographical means writing about holy people.
