XL. (117) And since all the things on the earth depend upon the heavenly bodies according to a certain natural sympathy, it is in heaven too that the ratio of the number seven began, and from thence it descended to us also, coming down to visit the race of mortal men. And so again, besides the dominant part of our mind, our soul is divided into seven divisions; there being five senses, and besides them the vocal organ, and after that the generative power. All which things, like the puppets in a raree show, which are moved by strings by the manager, are at one time quiet, and at another time in motion, each according to its suitable habits and capacities of motion. (118) And in the same way, if any one were to set about investigating the different parts of the body, in both their interior and the exterior arrangement, he will in each case find seven divisions. Those which are visible are as follow; ùthe head, the chest, the belly, two arms, and two legs; the internal parts, or the entrails, as they are called, are the stomach, the heart, the lungs, the spleen, the liver, and the two kidneys. (119) Again, the principal and dominant part in an animal is the head, and that has seven most necessary divisions: two eyes, an equal number of ears, two channels for the nostrils, and the mouth to make up seven, through which as Plato says, mortal things find their entrance, and immortal things their exit. For into the mouth do enter meat and drink, perishable food of a perishable body; but from out of it proceed wordsùthe immortal laws of an immortal soul, by means of which rational life is regulated.

XLI. (120) Again, the things which are judged of by the best of the senses, sight, partake of number according to their kind. For the things which are seen are seven; body, distance, shape, magnitude, colour, motion, tranquillity, and besides these there is nothing. (121) It also happens that all the changes of the voice amount to seven; the acute, the grave, the contracted, in the fourth place the aspirated sound, the fifth is the tone, the sixth the long, the seventh the short sound. (122) There are also seven motions; the motion upwards, the motion downwards, that to the right, that to the left, the forward motion, the backward motion, and the rotatory motion, as is most especially shown by those who exhibit dances. (123) It is affirmed also that the secretions of the body are performed in the aforesaid number of seven. For tears are poured out through the eyes, and the purifications of the head through the nostrils, and through the mouth the saliva which is spit out; there are, besides two other channels for the evacuation of the superfluities of the body, the one being placed in front and the other behind; the sixth mode of evacuation is the effusion of perspiration over the whole body, and the seventh that most natural exercise of the generative powers. (124) Again, in the case of women, the flux called the catamenia, is usually carried on for seven days. Also, children in the womb receive life at the end of seven months, so that a very extraordinary thing happens: for children who are born at the end of the seventh month live, while those who are born at the expiration of the eighth month are altogether incapable of surviving. (125) Again, the dangerous diseases of the body, especially when lasting fevers, arising from the distemperature of the powers within us, attack us, are usually decided about the seventh day. For that day determines the contest for life, allotting safety to some men, and death to others.
