Posidonius tells us that the Romans called Marcellus their sword, and Fabius their buckler; and that the vigor of the one, mixed with the steadiness of the other, made a happy compound that proved the salvation of Rome.
The two places are, however, not on the same meridian, and the distance between them was estimated, not measured. Two centuries later, Posidonius made another attempt between Alexandria and Rhodes; the bright star Canopus just grazed the horizon at the latter place, at Alexandria it rose 7 1/2 degrees.
Calippus has not apparently a central peak or any other features on the floor. CASSINI. This remarkable ring-plain, about 36 miles in diameter, is very similar in character to Posidonius. It has a very narrow wall, nowhere more than 4000 feet in height, and falling on the E. to 1500 feet.
I have applied myself to them from my youth, at no small expense of time and trouble; and I have been in the habit of philosophizing a great deal when I least seemed to think about it; for the truth of which I appeal to my orations, which are filled with quotations from philosophers, and to my intimacy with those very learned men who frequented my house and conversed daily with me, particularly Diodorus, Philo, Antiochus, and Posidonius, under whom I was bred; and if all the precepts of philosophy are to have reference to the conduct of life, I am inclined to think that I have advanced, both in public and private affairs, only such principles as may be supported by reason and authority.
Posidonius determined the arc of a meridian between Rhodes and Alexandria to be a forty-eighth part of the whole circumference an enormous calculation, yet a remarkable one in the infancy of astronomical science. Hipparchus introduced into geography a great improvement, namely, the relative situation of places, by the same process that he determined the positions of the heavenly bodies.
The circumference of the earth was conjectured, or ascertained, by Aristotle, Cleomedes, Posidonius, and Ptolemy respectively, to be 400, 300, 240, and 180 thousand stadia.
It may be added, that according to Strabo, Posidonius disbelieved the whole history of Scylax. In the Geographi Minores of Hudson, a voyage ascribed to Scylax is published; but great doubts are justly entertained on the subject of its authenticity. Dodwell is decidedly against it.
Quaest. iii. 28-30; and finally Epist. 90, Sec. 45, cp. Sec. 17. This last letter is a criticism on Posidonius, who asserted that the arts invented in primitive times were due to philosophers. Seneca repudiates this view: omnia enim ista sagacitas hominum, non sapientia inuenit.
A fine crescent-shaped mountain, 3000 feet high, stands near the S. side of the gap, and probably represents a portion of a once lofty wall. It will repay the observer to watch the progress of sunrise on the whole of the W. coast-line of the Mare up to Mount Argaeus. POSIDONIUS. This magnificent ring-plain is justly regarded as one of the finest telescopic objects in the first quadrant.
In the Hippodrome, however, she forgot everything in the present pleasure, and was happy enough in finding herself in the lowest row of places, in the comfortable seats on the shady side, belonging to Posidonius, the wealthy Magian.
