This paper argues that four Minoan glyptic images which combine trees, human figures, boats and the sea represent the combination of native Minoan with Canaanite religious ideas concerning a tree goddess who also had power over the sea. Each image is a glyph of the protective power of the Minoan tree deity over maritime voyaging within the Aegean and eastern Mediterranean. The empowerment of seafaring expeditions through supernatural patronage emphasises Minoan land-based power over the sea and extends the Cretan landscape outward to incorporate the seascape. It is further proposed that the images functioned in a protective talismanic capacity and that the containment of the iconographic motifs within the confines of gold rings and a stone seal linked the Minoan elites who owned these objects with the exotic aura of transculturality and power associated with overseas trade.
