Florence: Viviani, 1752. FIRST EDITION. A large folding plate depicting a solar eclipse, woodcut initials, head- and tailpieces. Contemporary paste-boards. An excellent copy. Item #16064
First edition of Ximenes’ astronomical observations according to Cassini’s tables to determine the solar ecliptic longitude. This was Ximenes’ first published work. His observations were recorded in Florence during the years 1752-1753 and described the solar eclipse of October 26, 1753 in twenty-two different European towns.
The solar eclipse of 1753 Oct 26 was a rare hybrid solar eclipse in which the eclipse path starts out as annular; further down the track it changes to total and then back to annular before the path ends. Of interest, it was preceded two weeks earlier by a partial lunar eclipse on October 12, 1753.
Ximenes (1716-1786) was an Italian mathematician, engineer, astronomer and geographer. In 1756, he founded the observatory of St. John in Florence (now named after him, the Ximenian Observatory). He is also known for having restored the fifteenth-century gnomon in the dome of Santa Maria del Fiore in Florence which he used to conduct his astronomical and physical observations.
