Among the curiosities of ancient credulity was the belief that certain birds possessed stones of remarkable talismanic virtue. One of these was supposed to be found in the brain of the vulture, which gave health to the finder and successful results when soliciting favors. Dioscorides gives an account of the use of an eagle-stone in detecting larceny. The _Alectorius_, a stone worn by the wrestler Milo, was so called from being taken out of the gizzard of a fowl. A stone like a crystal, as large as a bean, extracted from a cock, was considered by the Romans to make the wearer invisible. _Corvia_ was the name of a stone obtained from the nest of a crow. The swallow-stone was a Norman superstition, according to which the bird knows how to find on the seashore a stone that restores sight to the blind. Longfellow, in "Evangeline," says— "Seeking with eager eyes that wondrous stone which the swallow Brings from the shore of the sea, to restore the sight of her fledglings." _Birds Prognosticating Death._ In old times it was believed that certain birds prognosticated death. In Lloyd's "Stratagems of Jerusalem" (1602), he says: "By swallows lighting upon Pirrhus' tents, and lighting upon the mast of Mar. Antonius' ship, sayling after Cleopatra to Egypt, the soothsayers did prognosticate that Pirrhus should be slaine at Argos, in Greece, and Mar. Antonius in Egypt." He alludes to swallows following Cyrus from Persia to Scythia, from which the magi foretold his death. Ravens followed Alexander the Great in returning from India, and going to Babylon, which was a sure presage of his end. Among the Danish peasantry the appearance of a raven in the village is considered an indication that the parish priest is to die. "There is a common feeling in Cornwall," observes Mr. Hunt, "that the croaking of a raven over the house bodes evil to some of the family." Marlowe, in his "Rich Jew of Malta," described the "sad-presaging raven"— "That tolls The sick man's passport in her hollow beak, And in the shadow of the silent night Doth shake contagion from her sable wings." Gay, in "The Dirge," notices the presage— "The boding raven on her cottage sat And with hoarse croakings warn'd us of our fate." A number of crows are said to have fluttered about Cicero's head on the very day he was murdered. An evil prognostic attends the bittern in its flight. Bishop Hall, alluding to a superstitious man, says: "If a bittern flies over his head by night, he makes his will." Homer has immortalized the crane as foreboding disaster— "That when inclement winters vex the plain With piercing frosts, or thick descending rain, To warmer seas the cranes embodied fly, With noise and order, through the midway sky; To pigmy nations wounds and death they bring, And all the war descends upon the wing." Here is a saying that includes the magpie as a presager of death—
