These wonderful powers of the basilisk are attested by a host of learned persons, such as Galen, Avicenna, Scaliger, and others. Occasionally one would demur to some part of the tale while he admitted the rest. Jonston, a learned physician, sagely remarks, “I would scarcely believe that it kills with its look, for who could have seen it and lived to tell the story?” The worthy sage was not aware that those who went to hunt the basilisk of this sort took with them a mirror, which reflected back the deadly glare upon its author, and by a kind of poetical justice slew the basilisk with his own weapon. But what was to attack this terrible and unapproachable monster? There is an old saying that “everything has its enemy”—and the cockatrice quailed before the weasel. The basilisk might look daggers, the weasel cared not, but advanced boldly to the conflict. When bitten, the weasel retired for a moment to eat some rue, which was the only plant the basilisks could not wither, returned with renewed strength and soundness to the charge, and never left the enemy till he was stretched dead on the plain. The monster, too, as if conscious of the irregular way in which he came into the world, was supposed to have a great antipathy to a cock; and well he might, for as soon as he heard the cock crow he expired. The basilisk was of some use after death. Thus we read that its carcass was suspended in the temple of Apollo, and in private houses, as a sovereign remedy against spiders, and that it was also hung up in the temple of Diana, for which reason no swallow ever dared enter the sacred place. The reader will, we apprehend, by this time have had enough of absurdities, but still we can imagine his anxiety to know what a cockatrice was like. The following is from Aldrovandus, a celebrated naturalist of the sixteenth century, whose work on natural history, in thirteen folio volumes, contains with much that is valuable a large proportion of fables and inutilities. In particular he is so ample on the subject of the cock and the bull that from his practice, all rambling, gossiping tales of doubtful credibility are called _cock and bull stories_. Aldrovandus, however, deserves our respect and esteem as the founder of a botanic garden, and as a pioneer in the now prevalent custom of making scientific collections for purposes of investigation and research. Shelley, in his “Ode to Naples,” full of the enthusiasm excited by the intelligence of the proclamation of a Constitutional Government at Naples, in 1820, thus uses an allusion to the basilisk:
