.Benjamin Martins 1757 print showing the paths of 17 Transits of Venus from 918 to 2117. Special attention is given to the transit of 1639 - the only one previously observed - and to the forthcoming transit of 1761. The small print under the title reads “Published May 16th 1757 according to Act of Parliament & Sold by Mr Martin at his Shop in Fleet Street London. Price 1s 6d”. This is a rare survival: only one other copy of this print has been reported. Update 26/08/2008: Rob van Gent reports a third example of this print at the University Library Utrecht, Map Room, Collection Moll, Mappae Astronomicae 32 .
