This unique Pataikos1 is fully unconventional for two reasons: 1. this is a strange Janiform amulet because the two profiles and faces are quite different and 2. because it is unpierced for suspension, and thus not in accordance with numerous Janiform amulets, as described by both Andrews2 and in a number of examples in this survey (see #313, 369 and 381)
