Ededon magus hoc primum ferè dicītur usus,
Conscius in magica nihil esse potentius arte.
Post illum fertur famosa uenefica Circe
Hoc in præstigijs magicis specialiter usa.
This poem was reprinted (1854) in Migne's Patrologia. In 1799 Johann Beckmann issued an annotated variorum edition of Marbodeus (Marbodi Liber Lapidvm sev de Gemmis..., Göttingæ, 1799), in which there is a bibliography of the poem, the first edition of which appears to have been publisht in 1511, at Vienna, thirteen other editions being described. Beckmann adds many illustrative notes, and a notice of the Arabian Evax, who is supposed to have written the treatise de lapidibus. Not the least curious part is a French translation alleged to have been written in 1096, of which Chap. XIX. on the Magnet begins thus:
Magnete trovent Trogodite,
En Inde e precieus est ditte.
Fer resemble e si le trait,
Altresi cum laimant fait.
Dendor lama mult durement.
