Introduction

We discuss the rich strata of the esoteric in the work of the sage of Chalcis. Starting from the evidence for socially-esoteric teaching within Iamblichus' school, we move on to discuss his constructions of esoteric wisdom lineages – notably the tradition of ‘the theurgists’ – his employment of tropes of hiding and revealing, and the parameters of the Iamblichean ‘ineffable’.
