Pencil drawing made by Sir John Herschel (1792-1871) in 1824 at the 'Temple of Juno' at Girgenti in Sicily. The son of William Herschel, the famous astronomer, John Herschel was a renowned astronomer and scienist in his own right. Herschel made this drawing using a Wollaston Camera Lucida, a drawing aid that allowed the user to accurately delineate the scene being sketched. William Hyde Wollaston (1766-1828) invented the device in 1806 in an attempt to improve his sketching abilities. This was prompted by frustration at his inability to made sketches of the sights he saw during a walking holiday around Europe.
