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,” 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.
