quas digessere ccelum periti. la his quidem mille sexcentas adnotavere 

 stellas, insignes videlicet effectu vis uve." . . . (Plin. ii. 41.) "Hipparchus 

 nunquam satis laudatus, ut quo nemo magis approbaverit cognationem cum 

 homiue siderum aiiimasque nostras partem esse cceli, novam stellam et aliam 

 iu sevo suo genitam deprehendit, ej usque motu, qua die fulsit, ad dubitationem 

 est adductus, aune hoc ssepius fieret moverenturque et ese quas putamus 

 affixas ; itemque ausus rem etiam Deo improbain, adnumerare posteris stellas 

 ac sidera ad iiomen expuugere, organis excogitatis, per qnee singularum loca 

 atque magnitudines signaret, ut facile discerni posset ex eo, non modo an. 

 obirent nascerenturve, sed an omnino aliqua transirent moverenturve, item an 

 crescerent miauerenturque, coclo in hereditate cunctis relicto, si quisquam qui 

 cretionem earn caperet inventus esset" (Plin. ii. 26).

( 175 ) p. 91. It is to Aratusthat the Apostle Paul refers with implied praise 

 in his discourse at Athens (Acts, ch. xvii., v. 28). The name is not, indeed, 

 mentioned, but it is impossible to mistake the allusion to a passage from 

 Aratus (Phsen. v. 5) on the community of mortals with the Deity. Aratus is 

 also singularly enough referred to at a not very different date by Ovid 

 (Amor. i. 15). 



( 176 ) p. 92. Ideler, Uutersuchungen iiber den Ursprung der Sternnamen, 

 S. 3035. Baily, in the Mem. of the Astron. Soc., Vol. xiii. 1843, pp. 12 

 and 15, also treats of the dates according to the Christian era, with which we 

 should connect the observations of Aristyllus, as well as the Star-tables of 

 Hipparchus (128, not 140, B.C.), and of Ptolemy A.D. 138. 



( m ) p. 92. Compare Delambre, Hist, de I'Astr. anc. T. i. p. 1 84 ; T. ii. p. 

 260. The statement, that although Hipparchus always designates the stars 

 by their Right Ascension and Declination, yet that his Star-catalogue, like 

 that of Ptolemy, was arranged according to longitude and latitude, appears 

 to have little probability in its favour ; and is in contradiction to the Almagest, 

 book vii. cap. 4, where the relations to the Ecliptic are spoken of as some- 

 thing novel, tending to facilitate the knowledge of the movement of the fixed 

 stars round the pole of the Ecliptic. The Star-table with appended longitudes, 

 discovered by Petrus Victorius in a Medicean codex, and published with the 

 life of Aratus, at Florence, in 1567, is indeed attributed by him to Hipparchus 

 but without proof. It appears to be a mere transcript of Ptolemy's Table,
