It is not to be expected that so strange looking an animal as the Bat would escape mention in the legends which are so plentiful in the East. Signor Pierotti, who has done such signal service in the investigation of the Holy Land, gives a most remarkable semi-Mahommedan and semi-Christian legend respecting the origin of the Bat. The Mahommedans, unlike the generality of Jews, have always respected the memory of our Lord Christ--the Prophet Isa, as they call Him--ranking Him as one of the greatest of God's prophets, though they deny His actual divinity. In this curious legend, they have confused the forty days fast in the wilderness with the enforced Mahommedan fast called Ramadhan, much as the writers of the apocryphal gospels attributed to the holy family and the apostles certain phrases and acts of worship which were not in existence until several centuries after the Christian era. Towards the west of Jericho, there is a mountain which is identified both by Christians and Mahommedans as being the spot to which our Lord retired during his passion, and which, in consequence of this supposition, is called Kuruntun, or Quarantine. The reader, while perusing the following legend, must bear in mind that the fast of Ramadhan lasts for a month, and that from sunrise to sunset an entire abstinence from all kinds of nourishment is imperative upon all good Mussulmans. Even such luxuries as smoking or inhaling perfumes are forbidden, and although washing is permitted, the head must not be plunged under water, lest a few drops might find their way through the nostrils. In consequence of this strict prohibition, the moments of daybreak and sunset are noted with the most scrupulous care, the tables being set, pipes lighted, coffee prepared, and every luxury being made ready just before sunset, so that as the orb disappears beneath the horizon, the fasting multitudes may not lose a moment in satisfying their wants. A similar anxiety marks the approach of daybreak, because, as the first beams of the sun break through the darkness, neither food nor drink may pass their lips. We will now proceed to the Mahommedan legend, as it is given by S. Pierotti: "In this wild spot the great prophet Isa retired with his disciples to keep the holy month of the Ramadhan, afar from the tumults of the world. As the view westward was obstructed by the mountains of Jerusalem, and, consequently, the sunset could not be seen, he made, by the permission of God, an image in clay representing a winged creature; and, after invoking the aid of the Eternal, breathed upon it. Immediately it flapped its large wings, and fled into one of the dark caverns in the mountains. This creature was the Khopash (bat), which lies hid so long as the sun shines upon the world, and comes forth from its retreat when it sets. Every night, at the Moghreb, _i.e._ at the moment of breaking the fast, this bat fluttered round Isa, who then prepared himself with his disciples for prayer.
