CXXX NOTES. 



chap. 25) reached te t-he broken figure of a cow on the market-place of the 

 towu of Myrine in the island of Leranos. 



C 581 ) p. 359. For evidence of the visibility of these four objects, see S. 

 241, 338, 191, and 290, in Beer and Madler's " der Mond." It is scarcely 

 necessary to tell my readers that all that relates to the topography of the 

 Moon's surface is_ taken from the excellent work of these my two friends, of 

 one of whom, Wilhelm Beer, we have to lament the too early loss. The 

 study of lunar topography will be facilitated by the use of the fine map in a 

 single sheet ("Uebersichtsblatt"), published by Madler in 1837, three years 

 after the publication of the larger map of the Moon consisting of four sheets. 

 C 82 ) p. 359. Plut. de facie in orbe Luna, p. 726729, Wyttenb. The 

 passage is at the same time not without interest for ancient geography : see 

 Humboldt, Examen critique de 1'Hist. de la Geogr. T. i. p. 145. Respecting 

 other opinioas of the ancients, see Anaxagoras and Democritus, in Plut. de 

 plac. Philos. ii. 25 ; Parmenides, in Stob. p. 419, 453, 516 and 563, ed. 

 Heeren ; Schneider, Eclogse physicse, Vol. i. 433 443. (According to a 

 very remarkable passage of Plutarch, in the Life of Nicias, cap. 42, Anaxa- 

 goras himself, who termed " the mountainous Moon another Earth," made a 

 drawing of the Moon's disk : compare also Origenes, Philosophumena, cap. 8, 

 ed. Miilleri, 1851, p. 14.) I was once very much astonished to hear a very 

 accomplished Persian, of Ispahan, who had certainly never read a Greek book, 

 to whom I was shewing in Paris the spots on the Moon's fare through a large 

 telescope, propound the same hypothesis of reflection a. that of Agesianax, 

 referred to in the text, as prevalent in his own country. "It is ourselves 

 that we see in the Moon," said the Persian, " that is the map of our Earth." 

 One of the interlocutors in Plutarch's Conversation on the Moon would not 

 have expressed himself otherwise. Human beings in the Moon, if we could 

 imagine such to exist in the absence of air and water, would see the rotating 

 Earth with her spots suspended like one of our " Mappe-mondes," or " Maps 

 of the World," against a sky almost black in the day-time, occupying a space 

 fourteen times larger than that which the full moon covers to our eyes, and 

 always in the same place. The study of geography would, however, be some- 

 what impeded by our atmosphere with its continued variations dimming and 

 confusing the outlines of the continents. Comj/are Madler's Astr. S. 169;
