Sylvius noticed the venal valves. Fabricius, of Acquapendente, noticed that they all opened towards the heart. William Harvey, born in 1578, studied at Cambridge, and under Fabricius at Paula, and made the discovery of the nature of the arterial and venal circulations, and the complete double circulation, in 1616. Lancets of copper were disinterred in Pompeii in 1819, in the house of a Roman surgeon in the Via Consularis. They were in company with a probe, bullet-hook, catheters, forceps of
