The portrait of the swallow depicts the bird quite accurately with a forked tail, dark back and red breast.
Text Translation:
Of the swallow ‘The turtle-dove and the stork and the swallow observe the time of their coming. But my people know not the judgment of the Lord’ (see Jeremiah, 8:7). We have talked of the turtle-dove; that leaves the swallow and after it the stork to be discussed.
Isidore says this about it: ‘The swallow is so called because it does not feed on the ground but catches its food and eats it in the air. It is a twittering bird that flies in twisting, turning loops and circuits, is highly skilled in building its nest and rearing its young, and has also a kind of foresight because it lets you know when buildings are about to fall by refusing to nest on their tops. In addition, it is not harrassed by birds of prey nor is it ever their victim. It flies across the sea and winters there.’ The swallow is a tiny bird but of an eminently pious nature; lacking in everything, it constructs nests which are more valuable than gold because it builds them wisely. For the nest of wisdom is more precious than gold. And what is wiser than to have, as the swallow does, the capacity to fly where it likes and to entrust its nest and its young to the houses of men, where none will attack them. For there is something attractive in the way that the swallow accustoms its young from their earliest days to the company of people and keeps them safe from the attacks of hostile bird.
Then remarkably, the swallow creates a regularly-proportioned home for itself without any assistance, like a skilled craftsman. For it gathers bits of straw in its mouth and smears them with mud so that they stick together; but because it cannot carry the mud in its claws, it dips the tips of its wings in water, so that dust sticks to them easily and turns into slime, with which to gather to itself bits of straw or tiny twigs, a few at a time, and makes them stick. It makes the whole fabric of the nest in this fashion, in order that its young can live safely as if on a solid floor in houses on the ground, lest any of them insert a foot between the small gaps in the woven fabric or the cold should get to the very young. This conscientiousness is fairly common among most birds, yet what is distinctive about the swallow is its special loving care, shrewd intelligence and the extraordinary quality of its understanding.
Then there is its skill in the arts of healing: if its young are infected by blindness or pricked in the eye, it has some kind of healing power with which it can restore their vision. The swallow, as this example proves, can be taken to represent, in some cases, pride of mind; in others, the repentance of the afflicted heart. That the swallow signifies pride is illustrated by Tobit: When he lay down beside a wall, says Tobit, and fell asleep, it happened that warm excrement fell on his eyes from a swallows’ nest as he slept and he became blind (see Tobit, 2:10).
