In Scotland this number is known as the “Deil’s Dozen,” a phrase which has been supposed to have some connection with card-playing, there being thirteen cards in each suit of the “Deil’s Books.” John Jamieson, in his Scottish Dictionary, avows his inability to trace the superstition to its source, but believes that it includes the idea of the thirteenth being the Devil’s lot. The number thirteen is also sometimes known as a “baker’s dozen,” because it was formerly a common practice to give thirteen loaves for twelve, the extra piece being called the _in-bread_ or _to-bread_. This custom is supposed to have originated at a time when heavy fines were imposed for short weights, the additional bread being given by bakers as a precautionary measure.[551] In certain cases, contrary to the general rule, thirteen is accounted a fortunate numeral, or even as one possessing extraordinary virtues. Dr. Daniel G. Brinton, in “A Primer of Mayan Hieroglyphics” (p. 25), says that in the old language of the Mayas, an aboriginal tribe of Yucatan, the numbers nine and thirteen were used to denote indefinite greatness and supreme excellence. Thus a very fortunate man was possessed of nine souls, and the phrase, “thirteen generations old,” conveyed the idea of perpetuity. The “Demon with thirteen powers” was a prominent figure in the mythology of the Tzentals, a Mayan tribe. According to a widely prevalent popular impression, a brood is usually odd in number, and therefore it is folly to set an even number of eggs under a hen. In spite of the falsity of this idea, it is still quite customary to set thirteen eggs, an even number in this case being accounted unlucky. Gerald Massey, in “The Natural Genesis,” remarks that “there were thirteen kinds of spices set out in the Jewish religious service, along with the zodiacal number of twelve loaves of shew-bread. There are thirteen articles to the Hebrew faith, and the Cabalists have thirteen rules by which they are enabled to penetrate the mysteries of the Hebrew Scriptures. Thirteen are the dialectical canons of the Talmudical doctors for determining the sense of the law in all civil and ecclesiastical cases.” In England the day of twenty-four hours was formerly divided into thirteen parts, as follows:— 1. After midnight. 2. Cock-crow. 3. Between the first cock-crow and daybreak. 4. The dawn. 5. Morning. 6. Noon. 7. Afternoon. 8. Sunset. 9. Twilight. 10. Evening. 11. Candle-time. 12. Bed-time. 13. Dead of night.
