Molyneux’s Treatise of Dioptrics

William Molyneux’s Treatise of Dioptrics, 1692. This copy was given to Narcissus Marsh by Molyneux himself (as evidenced by Molyneux’s inscription, see left.) This 300 page book was the first English language book about optics. (For more on the Dioptrics of William Molyneux and his son, see “When an Eye is armed with a Telescope: The Dioptrics of William and Samuel Molyneux.” by Peter Abrahams.)

Among the other copies that Molyneux gave away was one sent to John Locke, which triggered a correspondence and a friendship that lasted until Molyneux’s death in 1698.
