i. History reports that Antonine, in the 2d year of his reign, 

 visited Egypt, and that, at the same time, a new Canicular period 

 commenced. Since Hadrian died, according to Spartianus, a.d. 

 139, July 10, Antonine's 2d year commenced with the same day 

 a.d. 140, and consequently the new Canicular period belongs to 

 A.D. 140, the 2d year of Antoninus Pius. Ideler, on the contrary, 

 referring the beginning of the Canicular period to the preceding
