Of glory, like the day-flood in its source."
"I have no where seen," says Mr. Southey in a note on these lines, "so circumstantial an account of its (the carbuncle's) wonderful properties as in a passage of Thuanus, quoted by Stephanius in his notes to Saxo-Grammaticus.
"Whilst the King was at Bologna, a stone, wonderful in its species and nature, was brought to him from the East Indies, by a man unknown, who appeared by his manners to be a Barbarian. It sparkled as though all burning, with an incredible splendour; flashing radiance, and shooting on every side its beams, it filled the surrounding air to a great distance with a light scarcely by any eyes endurable. In this also it was wonderful, that being most impatient of the earth, if it was confined, it would force its way, and immediately fly aloft; neither could it be contained by any art of man in a narrow place, but appeared only to love those of ample extent. It was of the utmost purity, stained by no soil nor spot. Certain shape it had none, for its figure was inconstant, and momentarily changing, and though at a distance it was beautiful to the eye, it would not suffer itself to be handled with impunity, but hurt those who obstinately struggled with it, as many persons before many spectators experienced. If by chance any part of it was broken off, for it was not very hard, it became nothing less."[398:A]
An account equally minute, and in terms nearly similar, occurs in Scot's Discoverie of Witchcraft, 1584, and both were probably taken from the same source, the writings of Fernel or Fernelius. This physician died in 1558; and his description, as copied by Scot, contributed, no doubt, to prolong the public credulity in this kingdom;
though the English philosopher attempts to explain the phenomenon by supposing that actual flame was concentrated and burning in the centre of the gem.
"Johannes Fernelius writeth of a strange stone latelie brought out of India, which hath in it such a marvellous brightnes, puritie and shining, that therewith the aire round about is so lightned and cleared, that one may see to read thereby in the darknes of night. It will not be conteined in a close roome, but requireth an open and free place. It would not willingly rest or staie here belowe on the earth, but alwaies laboureth to ascend up into the aire. If one presse it downe with his hand, it resisteth, and striveth verie sharplie. It is beautifull to behold, without either spot or blemish, and yet verie unpleasant to taste or feele. If any part thereof be taken awaie, it is never a whit diminished, the forme thereof being inconstant, and at everie moment mutable."[399:A]
The carbuncle was believed to be an animal substance generated in the body of a serpent, to possess a sexual distinction, the males having a star-formed burning nucleus, while the females dispersed their brilliancy on all sides in a formless blaze; and, like other transparent gems, to have the power of expelling evil spirits.
While on the subject of superstitious notions relative to luminous bodies, we may remark, that in the age of Shakspeare, the wandering lights, termed Will-o-wisp and Jack-o-Lantern, were supposed by the common people to be occasioned by demons and malignant fairies, with the view of leading the benighted traveller to his destruction. "Many tymes," says Lavaterus, "candles and small fiers appeare in the night, and seeme to run up and downe;—those fiers some time seeme to come togither, and by and by to be severed and run abroade, and at the last to vanish clean away. Somtime these fiers go alone in the night season, and put such as see them, as they travel by night, in great fear. But these things, and many suche lyke, have
their natural causes: and yet I will not denye, but that many tymes Dyvels delude men in this manner."[400:A]
Stephano, in the Tempest, attributes this phenomenon to the agency of a mischievous fairy: "Monster, your fairy, which, you say, is a harmless fairy, has done little better than played the Jack with us."[400:B]
