A vast number of engraved stones are in existence, to which the name "Abrasax-stones" has long been given. One particularly fine example was included as part of the Thetford treasure from fourth century Norfolk, UK. The subjects are mythological, and chiefly grotesque, with various inscriptions, in which ΑΒΡΑΣΑΞ often occurs, alone or with other words. Sometimes the whole space is taken up with the inscription. In certain obscure magical writings of Egyptian origin ἀβραξάς or ἀβρασάξ is found associated with other names which frequently accompany it on gems;[9] it is also found on the Greek metal tesseræ among other mystic words. The meaning of the legends is seldom intelligible: but some of the gems are amulets; and the same may be the case with nearly all.
