This lecture will explore the appearance of Indic ideas in insular and mainland Southeast Asia as reflected in archaeological artefacts and the earliest Sanskrit inscriptions, swiftly followed by the appearance of cult imagery closely linked to Vishnu in his multitudinous forms and Devi, the perennial goddess. A pre-eminence given to particular deities not seen in South Asia reflects a repurposing of these cults to indigenous purpose, as witnessed in monumental images of Vishnu, Surya, Krishna Govardhana, Kalkin-Hayagriva, Vishnu Anantasayin and Garudasana Vishnu, all of startling originality and all unmistakably “un-Indian” in style.
