The earliest Bronze Age Mediterranean primate representations on frescoes are found at the Aegean sites of Knossos (Crete) and Akrotiri (Thera). By contrast, monkeys have so far been missing from Mycenaean frescoes in mainland Greece. A fresco fragment of a cultic scene from Tiryns changes this; it depicts a bipedal partial lower body, with a hanging tail. This image, previously interpreted as a human wearing an animal hide, had already been suggested to represent a monkey. A re-examination of this miniature fresco identified various features that seem to confirm the representation of a monkey, most probably of a baboon-like primate. Assuming that the fresco from Tiryns is part of a cult scene, similar to those from Akrotiri, this adds a further image to a small corpus of Aegean depictions connecting monkeys with important female figures or deities. Furthermore, the Tiryns fresco fragment indicates that primates were not entirely absent from local Mycenaean iconography.
