It is plain that the Emperor has not borrowed this detailed descrip- 
tion from earlier writers, but has filled in some general description, 
in order to display his geographical learning. The chief points to be 
noted are—(1) he attributes this tripartition to Constantine; (2) he 
assigns Illyricum and Thrace to Constantius (instead of Constans), thus 
making his dominion co-extensive with what was afterwards the 
Eastern Empire. I presume that the author was led into this mistake 
by some vague notice, like that in Chronicon Pasch., which stated that 
Constans reigned év tots kata THY Iradiav pépeor, and did not mention 
Illyricum ; whence the Emperor assumed wrongly that Illyricum fell 
to the share of Constantius.

This notice differs from others in assigning implicitly Italy to 
Constantine. It agrees with Theophanes, Constantine Porph., and the 
Paschal Chronicle, in attributing the tripartition to Constantine I.

1 It seems not impossible that Dalmatius may have held a post in Mesopotamia, 
before he became Caesar, somewhat similar to that which Annibalianus held in 
Pontus and Armenia. It once occurred to me that Mesopotamiam, otf the Chron. 
Al., and rivam Goticam, of Anon. Val., might be referred to a common source by 
assuming that Muciay mapamotamulay (Moesia riparis, cf. Dacia riparis) had been 
corrupted to Mecorortautav. 
* That is, Gallia Cisalpina.
