On the Antiquity of the Chemical Art

The address challenges the view that modern chemistry began with the Arabian alchemist Geber in the eighth century, arguing that practical chemical knowledge long preceded formal theory. Beginning from Boerhaave’s definition of chemistry, the speaker traces technical traditions through Greek, Indian, Egyptian, and early Arab learning, notes Baghdad’s role as a translation and educational center under Abbasid patronage, and suggests ancient practices—including incendiary devices sometimes likened to Greek fire—reflect earlier chemical arts. Emphasis is placed on unwritten, traditional workmanship, the diffusion of knowledge via translations, and the intent to follow chemical ideas further back than commonly credited.
