HIPPARCHUS.--Except under a low sun, this immense walled-plain is by no means so striking an object as a glance at its representation on a chart of the moon would lead one to expect; for the border, in nearly every part of it, bears unmistakable evidence of wreck and ruin, its continuity being interrupted by depressions, transverse valleys, and gaps, and it nowhere attains a great altitude. This imperfect enclosure extends 97 miles from N. to S., and about 88 miles from W. to E., and in shape approximates to that of a rhombus with curved sides. One of the most prominent bright craters on its border is Hipparchus G, on the E. Another, of about the same size, is Hipparchus E, on the N. of
. On the W. there is a moderately bright crater, Hipparchus F; and S. of this, on the same side, two others, K and I. The interior is crossed by many ridges, and near the centre includes the relics of a low ring, traversed by a narrow rill-like valley. Schmidt shows a cleft running from F across the floor to the S. border.
[A valuable monograph of Hipparchus, by Mr. E.B. Birt, was published in 1870.]

3 stars of Orion

(ca. 190 BC – ca. 120 BC) was a Greek astronomer, geographer, and mathematician of the Hellenistic period. He is known to have been a working astronomer at least from 147 BC to 127 BC. Hipparchus is considered the greatest astronomical observer and, by some, the greatest overall astronomer of antiquity.
