Sir William Gell (1777 - 1836) was an archæologist involved in excavating Pompeii. He was a fellow of the Royal Society and the Society of Antiquaries of London.
Gell illustrated the the excavation of Pompeii when it was little known. He had special permits for visiting the excavations at all hours. He sketched using a camera lucida, and had his sketches turned into wonderfully detailed engraved prints.
His engravings were exact and detailed so became standard material for students for a long time. They are still useful to archæologists.
Here are some of his engravings of Pompeii for you to choose from. They are original antiques, made in 1717.
