|Main Creator:||Emslie, John Philipps, 1813-1875, engraver.|
This was issued as one of a set of twelve hand-tinted astronomical prints with explanatory card, ca. 1846-1860. This astronomical diagram drawn and engraved by John Philipps Emslie, shows some of the craters and seas of the moon as it appears through a telescope. This moon map illustrates both the difference in brightness of the lunar surface along with the form and shape of the lunar mountains and craters - these are shown together for clarity as the former is best been when the Moon is full while the latter is most clear when the Moon is half lit. With description by Dr. William Scoresby following his use of the great telescope constructed by William Parsons, 3rd Earl of Rosse at Birr Castle, Co. Offaly [construction of the telescope was completed in 1845]. Mounted in simillar manner as protean views suggesting that aquatint should be viewed by being held up to the light. Printed at foot of sheet: "The appearance of the Moon as seen by Lord Rosse's great telescope is thus described by Dr. Scoresby "It appeared like a Globe of Molten Silver, and every object of the extent of a hundred yards was quite visible. Edifices, therefore of the size of York Minister might be easily perceived if they had existed. But there was no appearance of anything of that nature, neither was there any indication of the existence of water or of an atmosphere. There was a vast number of extinct volcanoes, several miles in breadth; through one of them there was a line in continuance of one, about 150 miles in length which ran in a straight direction like a railway. The general appearance however was like one vast ruin of nature". James Reynolds’ educational diagrams received a prize medal at the International Exhibition of 1862.
