St Vincent's (Lesser Antilles, Caribbean) archaeological record is rich in images depicted by a variety of fired clay artefacts. Prominent among them are small modelled and incised zoomorphic heads known as "adornos" that decorated the rims, handles and exteriors of pottery vessels made by the first agriculturalists on the island (the Saladoid culture from the Venezuela area by 250 BC). This work sets out to contribute a systematic study of both a formal and descriptive classification, as well as an iconographic analysis of the basic images represented.
