Prester John was a legendary Christian patriarch, presbyter, and king. Stories popular in Europe in the 12th to the 17th centuries told of a Church of the East patriarch and king who was said to rule over a Christian nation lost amid the pagans and Muslims in the Orient. The accounts were often embellished with various tropes of medieval popular fantasy, depicting Prester John as a descendant of the Three Magi, ruling a kingdom full of riches, marvels, and strange creatures.

In Christianity, the Biblical Magi, also known as the Three Wise Men, Three Kings, and Three Magi, are distinguished foreigners who visit Jesus after his birth, bearing gifts of gold, frankincense, and myrrh in homage to his birth. As such, the Magi are commemorated on the feast day of Epiphany—sometimes called "Three Kings Day"—and commonly appear in the nativity celebrations of Christmas.
