1. The magpie, a party-colored bird of the genus Corvus. It is sometimes written pye.
2. The old popish service book, supposed to be so called from the different color of the text and rubric, or from litera picata, a large black letter, used at the beginning of each order.
3. Printers' types mixed or unsorted. Cock and pie, an abjuration by the pie or service book, and by the sacred name of the Deity corrupted. – Shak.
