Petau. loc. cit. M. Ideler asserts that this concurrence of the heliacal rising of Sirius also took place in 2782 before Christ. (Historical Researches in M. Halma’s Ptolomée, vol. iv. p. 37.) But with regard to the Julian year 1598 after Christ, which is also the last of a great year, Petau and Ideler differ much from each other. The latter refers the heliacal rising of Sirius to the 22d July; the former to the 19th or 20th of August.
