The 'rhetoric of paintings' in seventeenth-century Jesuit literature is concerned with bringing pictures to life and granting them speech. Since the sixteenth century the prefaces to illustrated books had been repeating that the 'body' (or picture) requires a 'soul', that words and images complement each other. The Jesuit 'theology of the visible' and 'philosophy of the image' has fostered a rich iconology founded on the incarnation of the Word, i.e. on the principle of a Logos made image.
