It is associated with a number of ridges trending towards the region N. of Aristarchus and Herodotus.
Now, by comparing the apparent size of the sun with the apparent size of the moon which, as we have seen, Aristarchus has already measured he is able to tell us that, the sun is "more than 5832 times, and less than 8000" times larger than the moon; though his measurements, taken by themselves, give no clew to the actual bulk of either body.
"If we admit these six hypotheses," Aristarchus continues, "it follows that the sun is more than eighteen times more distant from the earth than is the moon, and that it is less than twenty times more distant, and that the diameter of the sun bears a corresponding relation to the diameter of the moon; which is proved by the position of the moon when dichotomized.
Anxious to meet Pharnabazus and make sure of his bribe, Anaxibius impressed his parting injunction upon Aristarchus to sell for slaves all the Cyreians whom he might find at Byzantium on his arrival, and then pursued his voyage along the southern coast of the Propontis to Parium.
Various propositions deal with other relations of the shadows which need not detain us since they are not fundamentally important, and we may pass to the final conclusions of Aristarchus, as reached in his propositions ten to nineteen. "Proposition sixteen. The diameter of the sun is to the diameter of the earth in greater proportion than nineteen to three, and less than forty-three to six.
There salute you Aristarchus my fellow-prisoner, and Mark nephew to Barnabas, concerning whom ye have received injunctions; if he come unto you, receive him, and Jesus, who is called Justus, who are of the circumcision.

The mountain plateau N. of Aristarchus deserves careful scrutiny, as it abounds in detail and includes many short clefts. HARBINGER, MOUNTAINS. A remarkable group of moderate height, mostly extending from the N.W. towards Aristarchus.
Without stopping to alight on the outer slopes of the great ring-shaped range of peaks which composed Aristarchus, we sailed over their rim and looked down into the interior.
The Sectio Canonis, which has come down under the name of Euclid, can, however, hardly be his in its present form. Accepting Heraclides's view that the earth rotates about its own axis, Aristarchus went further and put forward the hypothesis that the sun itself is at rest, and that the earth, as well as Mercury, Venus, and the other planets, revolve in circles about the sun.
The one, it appears, alleges in two short verses that Nicias owes him money; the other, like an Aristarchus, cavils at them. I, like an old critic, am to decide whether they are Nicias's or spurious."
