SEFFAVRTH ON THE THEORY OF THE MOON'S MOTIONS. 465 



July 1 6th, 45m. past noon, Roman time, obscuration n inches. 

 Since the longitude of the 15 was shorter by 2° 35', the eclipse 

 was smaller in Rome, and total in Africa only. The eclipse in 

 the preceding year, July 27. 2ih. P. T., or, according to the Table 

 on p. 429, 23IL 22m. in Rome, likewise took place about noon ; 

 but, the 15 being n°, i.e. about 8° E., the obscuration was great 

 only in Northern Italy.

 curve 30 , 65 , 64 . Theophanes (p. 31 ed. Goar) reports that, 

 within the 10th year of Constantius (a.d. 346), on the 6th day of 

 Da^sius (June 6th), and within the 3d hour of the day, a total, or 

 nearly total, eclipse of the sun took place in Constantinople (zw

 we read in Cedrenus. Eusebius and Hieronymus (Chr.ii. p. 183) 

 refer the same eclipse to the same 10th year of Constantius. The 

 position of Constantinople presumed to be 31 10' Long, and 41 

 N. Lat., the sun rose there on June 5th about 4h. 40m. ; conse- 

 quently the 3d hour of the day commenced about 6h. 26m. local 

 time, and, in consequence of the parallax, the eclipse began nearly 

 two hours earlier. According to our Table (p. 429), however, 

 the conjunction was nearly ih. 34m. later, which agrees with 

 Theophanes and Cedrenus. Even Petavius found that, accord- 

 ing to his Lunar Tables, the eclipse happened one hour too 

 early. This eclipse, moreover, was partial in Constantinople.

59. © -r-347, Oct. 20th, 3h., 15 i4°E., Constantinople. Theo- 

 phanes reports that in the course of the nth year of Constantius, 

 "on a Monday," a partial eclipse of the sun occurred (Theoph. 

 p. 32 ed. Goar : b TjXtoz TtdXiv ahypqpbztpoc, yerovsv ip wpa ft 

 z?^ xupiaxqz ^jp-spaq). The obscuration amounted, as Petavius 

 calculated, to 7 inches ; but, according to our Table (p. 429), the 

 longitude of 15 was shorter by 2° 33', and hence the obscm-ation 

 was greater. But this eclipse happened on a Tuesday, and not 

 on a Sunday. The only eclipse coinciding about that time with 

 a Sunday was that of a.d. 345, June i6th, ih., U i°E., or rather 

 (p. 429) i° 34' W., which must have been a nearly total one in 

 Constantinople ; for the central shadow of the moon traversed at 

 noon, as Pingre states, the 16th degree of north latitude, but,
