C. Bonner, Amulets Chiefly in the British Museum, Hesperia 20, 1951, 301-345, no. 14.

Obv. So called gryllus, a fanciful combination of a bearded human mask (to l.) and a ram's head (to r.) holding an ear of grain in its mouth, supported by the legs of a cock. The upper part of the design, which in other examples often shows the head and neck of a horse, is chipped off. In the field, directly in front of the human face, is a lion running towards the top of the stone. Separate elements are not infrequently introduced in the field of such designs, for example the dolphin and palm branch on a stone from a Roman bath west of the Areopagus, recently published by H. A. Thompson (Hesperia, 18 (1949), p. 226 and pl. 46, 5; cf. the closely similar Berlin specimen, in Furtwängler, Beschreibung, No. 8532); but I have not seen a lion so placed on any other examples.
Rev. Ibis (symbol of Hermes Thoth) to l. holding a caduceus under its wing. The bird's head is encircled with a nimbus and rays (partly broken away), perhaps an indication that the ibis here does duty for the phoenix also (SMA, p. 60, and Pl. 5, Nos. 103 /CBd-1046/ 104 /CBd-198/). Under the bird's feet is a rectangle enclosing the word IAW. In field at r., arranged vertically, a star and AZ; at l. two characters and Β lying horizontally.
Obsidian. Upright oval, 24x 17. Chipped at top.
