(6) And twice in every year the day and night are equal, for on the original attack, when it (the sun) went forth from its first degree (khûrdak), the day and night were equal, it was the season of spring; when it arrives at the first degree of Kalakang (Cancer) the time of day is greatest, it is the beginning of summer; when it arrives at the sign (khûrdak) Tarâgûk (Libra) the day and night are equal, it is the beginning of autumn; when it arrives at the sign Vahîk (Capricorn) the night is a maximum, it is the beginning of winter; and when it arrives at Varak (Aries) the night and day have again become equal, as when it went forth from Varak.

(20) For the motion of the sun from solstice to solstice is completed in six months - in the course of which, at one time the leaves fall, and at another plants bud and seeds come to maturity. And they say that the embryo is perfected exactly in the sixth month, that is, in one hundred and eighty days in addition to the two and a half, as Polybus the physician relates in his book On the Eighth Month, and Aristotle the philosopher in his book On Nature. Hence the Pythagoreans, as I think, reckon six the perfect number, from the creation of the world, according to the prophet, and call it Meseuthys and Marriage, from its being the middle of the even numbers, that is, of ten and two. For it is manifestly at an equal distance from both.

(6) But the variety of disposition arises from inordinate affection to material things. And for this reason, as they appear to me, to have called night Euphrone; since then the soul, released from the perceptions of sense, turns in on itself, and has a truer hold of intelligence (Fronhsis). Wherefore the mysteries are for the most part celebrated by night, indicating the withdrawal of the soul from the body, which takes place by night. "Let us not then sleep, as do others; but let us watch and be sober. For they that sleep, sleep in the night; and they that are drunken, are drunken in the night. But let us who are of the day be sober, putting on the breastplate of faith and love, and as an helmet the hope of salvation." And as to what, again, they say of sleep, the very same things are to be understood of death. For each exhibits the departure of the soul, the one more, the other less; as we may also get this in Heraclitus: "Man touches night in himself, when dead and his light quenched; and alive, when he sleeps he touches the dead; and awake, when he shuts his eyes, he touches the sleeper." "For blessed are those that have seen the Lord," according to the apostle; "for it is high time to awake out of sleep. For now is our salvation nearer than when we believed. The night is far spent, the day is at hand. Let us therefore cast off the works of darkness, and put on the armour of light." By day and light he designates figuratively the Son, and by the armour of light metaphorically the promises.
