This paper discusses Aristotle's references to a ζῷον in his Poetics (1450b34–51a4 and 1459a20) and evaluates their implications. The usual interpretation, ‘living creature’ or ‘animal’, is one-sided, because the word ζῷον is Aristotle's paradigm of homonymy, applying as it does to both the human being and the drawing (Cat. 1a1–6). After an examination of the two passages containing such references and their contexts, other passages by Aristotle and earlier writers (Plato, Alcidamas and Gorgias) that may shed light on the issue are analysed. The conclusion reflects on the relevance of the interpretation as ‘figure’ for the premises and purpose of the Poetics.
