Sometimes, when travellers have been exploring the chambers of ruined buildings, or have endeavoured to penetrate into the recesses of rocky caves, they have been repelled by the bats which had taken up their habitation therein. No sooner does the light of the torch or lamp shine upon the walls, than the clusters of bats detach themselves from the spots to which they had been clinging, and fly to the light like moths to a candle. No torch can withstand the multitude of wings that come flapping about it, sounding like the rushing of a strong wind, while the bats that do not crowd around the light, dash against the explorers, beating their leathery wings against their faces, and clinging in numbers to their dress. They would even settle on the face unless kept off by the hands, and sometimes they force the intruders to beat a retreat. They do not intend to attack, for they are quite incapable of doing any real damage; and, in point of fact, they are much more alarmed than those whom they annoy. Nocturnal in their habits, they cannot endure the light, which completely dazzles them, so that they dash about at random, and fly blindly towards the torches in their endeavours to escape. If, then, we keep in mind the habits of the bats, we shall comprehend that their habitations must be inexpressibly revolting to human beings, and shall the better understand the force of the prophecy that the idols shall be cast to the bats and the moles. There is another, and a very forcible passage, in which the Bat is mentioned. In the apocryphal book of Baruch, the Bat is used as a lively image of something peculiarly repulsive and hateful. Baruch was the secretary and faithful friend of Jeremiah the prophet, and Chapter VI. of the book of Baruch purports to be an epistle of Jeremiah to the captive Jews about to be led away to Babylon. After showing that they had brought their fate upon themselves by neglecting the worship of the true God, and prophesying that they would remain in captivity for seven generations, the writer proceeds, in a strain of scathing and sustained satire, to deride the idols which they had adored, and to censure the infamous ceremonies that formed part of the worship. After describing the idols, made splendid with silver and gold, whose hands hold sceptres, and axes, and wands, and yet cannot save themselves from robbers; whose tongues are polished by the workman and yet cannot speak a word; whose eyes are covered with dust which they cannot wipe off for themselves; he proceeds as follows: "Their hearts are gnawed upon by things creeping out of the earth; and when they eat them and their clothes they feel it not. Their faces are blacked through the smoke that cometh out of the Temple. Upon their bodies and heads sit bats, swallows and birds, and the cats also. By this ye may know that they are no gods; therefore fear them not."
