Now the Pythagorean symbols were connected with the Barbarian philosophy in the most recondite way. For instance, the Samian counsels “not to have a swallow in the house;” that is, not to receive a loquacious, whispering, garrulous man, who cannot contain what has been communicated to him. “For the swallow, and the turtle, and the sparrows of the field, know the times of their entrance,”[754] says the Scripture; and one ought never to dwell with trifles. And the turtle-dove murmuring shows the thankless slander of fault-finding, and is rightly expelled the house. “Don’t mutter against me, sitting by one in one place, another in another.”[755] The swallow too, which suggests the fable of Pandion, seeing it is right to detest the incidents reported of it, some of which we hear Tereus suffered, and some of which he inflicted. It pursues also the musical grasshoppers, whence he who is a persecutor of the word ought to be driven away. “By sceptre-bearing Here, whose eye surveys Olympus, I have a trusty closet for tongues,” says Poetry. Æschylus also says: “But I, too, have a key as a guard on my tongue.” Again Pythagoras commanded, “When the pot is lifted off the fire, not to leave its mark in the ashes, but to scatter them;” and “people on getting up from bed, to shake the bed-clothes.” For he intimated that it was necessary not only to efface the mark, but not to leave even a trace of anger; and that on its ceasing to boil, it was to be composed, and all memory of injury to be wiped out. “And let not the sun,” says the Scripture, “go down upon your wrath.”[756] And he that said, “Thou shalt not desire,”[757] took away all memory of wrong; for wrath is found to be the impulse of concupiscence in a mild soul, especially seeking irrational revenge. In the same way “the bed is ordered to be shaken up,” so that there may be no recollection of effusion in sleep, or sleep in the day-time; nor, besides, of pleasure during the night. And he intimated that the vision of the dark ought to be dissipated speedily by the light of truth. “Be angry, and sin not,” says David, teaching us that we ought not to assent to the impression, and not to follow it up by action, and so confirm wrath. Again, “Don’t sail on land” is a Pythagorean saying, and shows that taxes and similar contracts, being troublesome and fluctuating, ought to be declined. Wherefore also the Word says that the tax-gatherers shall be saved with difficulty.[758]
