Commentano d’Ipparco sopra Arato, la libra non 
comparisce e non si nomina maty come ognuno puo as^ 
sicurarsene da per se (Testa, del Zodiaco, p. 21 and 
46). I ought here to observe, that the passage of 
Hipparchus, which I have cited, is found in the com- 
mentary divided into three books ; and not in the 
fragment, which appears apocryphal, and which is at- 
tributed sometimes to Hipparchus, and at other times 
to Eratosthenes. The words ^vySg and jugum may, 
without doubt, denote a couple, whatever is double 
or paired; but the prose writers in this sense em- 
ploy rather than and Ptolemy places Ta 
in opposition with which he would not 
do, if fuyo’c; and t.yjy'k were the explanation of %v^od. 
The star,” he says, which according to them 
(the Chaldeans) is in the basin of the Scales^ and 
according to our principles (according to our man- 
ner of dividing the Zodiac), in the claws of the Scor- 
pion,” * 
* Ptolem , ed. Bas., p. 232. Theon, in his commentary, often 
employs, intead of and Ta ^yot the word ; a substitution, 
which leaves no doubt of the signification of {wyoj. Manetho says, ‘‘ the 
claws of the Scorpion, which the holy men call the beam of the Scales 
and this passage would be very remarkable, if it were proved that Manetho, 
the astronomer, is the same person as the author of the A*<yt; 9 rT»as«a , 
and that consequently he lived under the reign of Ptolemy Philadelphus. 
(Fabricii Bibl. Grseca, 1795, tom. 4, p. 135 — 139.) The word ^vyhs is 
not found in the asterisms of Eratosthenes (ed. Schaubach, c. 7, p. 6), 
but in the Commentary on Aratus (Uran. p. 142), which bears falsely 
the name of this ancient astronomer, and which appears to belong to 
Achilles Tatius.
