Robert Hooke and Christopher Wren's interest in ancient buildings has been noted by historians of architecture and natural philosophy alike. The two men used to meet to discuss descriptions – both verbal and visual – and models of ancient buildings that had long since disappeared and were known only through ancient accounts, or that remained only in a ruined or altered form. These included the Temple of Solomon, described at different places in the Bible, Porsenna's tomb, cited as an example of extravagance by Pliny the Elder, and the Hagia Sophia. In 1675, Hooke recorded such a meeting in his diary: ‘With Sir Chr. Wren. Long Discourse with him about the module [model] of the Temple at Jerusalem’.
