Three magic words to make even an old, weak horse run like a champion:
"You turn his face eastward and you whisper into his ear, three times, the words: 'Nicander, Melchior, and Merchizard.'" —Umberto Eco, The Name of the Rose
Nicander is the name of an Egyptian saint. Melchior is the name of one of the Three Magi. Merchizard remains a mystery.
