n the first to be viewed through a telescope. The eclipse was only a large partial one. The following record of the fact is due to Tycho Brahe.[137] "The beginning of the eclipse of the Moon as observed through the Roman telescope, appeared like a dark thread in contact with the shadow"--a description which cannot be said to be unduly explicit. In 1620, on June 15, there was a total eclipse of the Moon, when during the total phase "the Moon was seen with great difficulty. It shone, moreover, like the thinnest nebula, far fainter than the Milky Way, without any copper tinge. About the middle of the second hour nothing at all could be seen of the Moon with the naked eye, and through the telescope so doubtfully was anything seen that no one could tell whether the Moon was not something else." It is expressly stated, however, that the sky was quite clear. Kepler also observed this eclipse, and says that the Moon quite disappeared, though stars of the 4th and 5th magnitudes were plainly visible.[138] In this same year 1620, there was on December 9 another total eclipse, when "the Moon altogether disappeared so that nothing could be seen of it, though the stars shone brightly all around: she continued lost and invisible for a quarter of an hour more or less." This observation seems to have been made at Ingolstadt. Wendelinus mentions the eclipse of April 14, 1623, in connection with the question of the visibility of the Moon when totally eclipsed. He says, "but sometimes it so far retains the light derived from the Sun that you would doubt whether any part of it were eclipsed." This eclipse was observed by Gassendi, and if the above record is correct, it is the more remarkable seeing that the eclipse was not total, only 11/12ths of the Moon's diameter being obscured. On April 25, 1642, on the occasion of a total eclipse, Hevelius[139] noted that the Moon wholly disappeared when immersed in the Earth's shadow. Crabtree is stated by Flamsteed[140] to have observed this eclipse, but he does not plainly state that he lost sight of the Moon. Crabtree or his editor dates this eclipse for April 4; Ferguson for April 15. There appears to be some muddle as between "old style" and "new style." Ferguson professing to be N.S. is evidently wrong. Hevelius gives the double date, 15/25, which is evidently right. On June 16, 1666, the Moon was seen in Tuscany to rise eclipsed, the Sun not having yet set in the W. On May 26, 1668,
