Περὶ Ἴσιδος και Ὀσίριδος Plutarch
42 The Egyptians have a legend that the end of Osiris s life came on the seventeenth of the month, on which day it is quite evident to the eye that the period of the full moon is over.Fourteen days, or one half of a lunar month, before the ἕνη καὶ νέα, if the lunar month could ever be made to square with any system of chronology! Because of this the Pythagoreans call this day the Barrier, and utterly abominate this number. For the number seventeen, coming in between the square sixteen and the oblong rectangle eighteen, which, as it happens, are the only plane figures that have their perimeters equal to their areas,That is: 4 x 4 = 16 and 4 + 4 + 4 + 4 = 16: so also 3 x 6 = 18 and 3 + 6 + 3 + 6 = 18. bars them off from each other and disjoins them, and breaks up the ratio of eight to eight and an eighthThat is, 1/8 of a number added to itself: thus 16 + 16/8 = 18. Eighteen, therefore, bears the epogdoon relation to sixteen, which is broken up by the intervention of seventeen, an odd number. by its division into unequal intervals.
