in natural history, a kind of figured stone, of a round shape, but rugged, and befit with eminences, celebrated on account of its use in divination. The word is originally Greek, ἀμφικόμης, q. d. ἀ-τριγγεῖς κοντά, or hairy on all sides. This stone is also called Erytus, Erythras, Amateria, probably on account of its supposed power of creating love. The amphicome is mentioned by Democritus and Pliny, tho' little known among the moderns. Mercatus takes it for the same with the lapis lubricatus, of which he gives a figure.
