William Whiston’s print of “The Transits of Venus and Mercury over the Sun at their Ascending and Descending Nodes for Two Centuries and an half”, dated 22 october 1723. Despite Edmond Halley’s emphasis on Venus, Whiston considered that Mercury was as likely to provide a reliable value for the Sun’s parallax. The print is signed “London. Printed for and Sold by I. Senex at the Globe against St Dunstans Church in Fleet Street”.
