t the comet is one of the planets, but that it appears at great intervals of time and only rises a little above the Viktor Claesson Pelipaita horizon. This is the case with Mercury too; because it only rises a little above the horizon it often fails to be seen and consequently appears at great intervals of time.
A view like theirs was also expressed by Hippocrates of Chios and his pupil Aeschylus. Only they say that the tail does not belong to the comet iself, but is occasionally assumed by it on its course in certain situations, when our sight is reflected to the sun from the moisture attracted by the comet. It appears at greater intervals than the other stars because it is slowest to get clear of the sun and has been left behind by the sun to the extent of the whole of its circle before it reappears at the same point. It gets clear of the sun both towards the north and towards the south. In the space between the tropics it does not draw water to itself because that region is dried up by the sun on its course. When Blank Pelipaita it moves towards the south it has no lack of the necessary moisture, but because the segment of its circle which is above the horizon is small, and that below it many times as large, it is impossible for the sun to be reflected to our sight, either when Jean-Francois Gillet Pelipaita it approaches the southern tropic, or at the summer solstice. Hence in these regions it does not develop a tail at all. But when it is visible in the north it assumes a tail because the arc above the Nike Air Max 270 Womens horizon is large and that Mario Gaspar Pelipaita below it small. For under these circumstances there is nothing to prevent our vision from being reflected to the sun.
These views involve impossibilities, some of which are common to all of them, while others are peculiar to some only.
This is the case, first, with those who say that the comet is one of the planets. For all the planets appear in the circle of the zodiac, whereas many comets have been seen outside that circle. Again more comets than one have often appeared simultaneously. Besides, if their tail is due to reflection, as Aeschylus and Hippocrates say, this planet ought sometimes to be visible without a tail since, as they it does not possess a tail in Poland Drakt every place in which it appears. But, as a matter of fact, no planet has been observed besides the five. And all of them are often visible above Thomas Meunier Pelipaita the horizon together at the Jordan Henderson Pelipaita same time. Further, comets are often found to appear, as well when all the planets are visible as when some are not, but are obscured by the neighbourhood of the Belstaff Maldon Jackor sun. Moreover the statement that a comet only appears in the north, with the sun at the summer solstice, is not true either. The great comet which appeared at the time of the earthquake in Achaea and the tidal wave Eindhoven Pelipaita rose due west; and many have been known to appear in the south. Again in the archonship of Euclees, son of Molon, at Athens Adidas Campus 80s there appeared a comet in the north in Air Jordan 9 Women the month Gamelion, the sun being about the winter solstice. Yet they themselves admit that reflection over so great a space is an impossibility.
An objection that tells equally against those wholinks:
