The Egyptians worshipped the seven planets, and Herodotus tells us of their seven castes. So with the Babylonians. From them was derived the Jewish week. Hesiod, according to Eusebius, said "The seventh is the sacred day." What he says in his _Works and Days_ is, "On the seventh day Latona brought forth Apollo"; and Æschylus, in his _Seven Against Thebes_, says the number Seven was sacred to Apollo. The moon periods were sacred as measuring time and also in connection with female periodicity. Man discovered the month before the year. Hence the moon was widely worshipped. The worship of the queen of heaven in Palestine is alluded to in Jer. vii. 18 and xliv. 17. The superstition of the new moon bringing luck has descended to our own time. When the year was reckoned by thirteen moons of twenty-eight days, thirteen was the lucky number; but when this was changed for the twelve months of solar time, thirteen became one too many. The Parsee Bundahisli, according to Gerald Massey, exhibits seven races of men--(1) the earth-men, (2) water-men, (3) breast-eared men, (4) breast-eyed men, (5) one-legged men, (6) batwinged men, (7) men with tails. Section 7 of the Kabbalistic Sepher Yezirah* says, "The seven planets in the world are Saturn, Jupiter, Mars, Sun, Venus, Mercury, Moon. Seven days in the year are the seven days of the week; seven gates in man, male and female, are two eyes, two ears, two nostrils and the mouth." Again, section 15 says, "By the seven double consonants were also designed seven worlds, seven heavens, seven lands, seven seas, seven rivers, seven deserts, seven days a week, seven weeks from Passover to Pentecost, there is a cycle of seven years, the seventh is the release year, and after seven release years is jubilee. Hence God loves the number seven under the whole heaven." * Trans, by Dr. I. Kalisch, pp. 27 and 81.
