NOTES. 243 



eornrnentario d'Ipparco sopra Arato, la libra non 

 comparisce e non si nomina mai, 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 %uy$g and jugum may, 

 without doubt, denote a couple, whatever is double 

 or paired ; but the prose writers in this sense em- 

 ploy rather fyvyoq than £uyoq, and Ptolemy places to. 

 Xvya in opposition with %v]A#/, which he would not 

 do, if %uydc, and %vyx were the explanation of %v\K»l. 

 " 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 %vyo( and rx fyyd the word \W^xi ; a substitution, 

 which leaves no doubt of the signification of fuyoj. 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/irriasxot, 

 and that consequently he lived under the reign of Ptolemy Philadelphus. 

 (Fabricii Bibl. Graeca, 1795, torn. 4, p. 135—139.) The word £vyos 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.
