If this note should prove persuasive, the credit will not belong to me; if not, I must accept the blame for publishing something not published by its author.Recently I acquired an offprint of Cumont's article ‘La plus ancienne géographie astrologique’ (Klio ix, 1909, 263–273) which deals with the doctrine that divides up the various countries among the signs of the zodiac. On p. 265, where the list of Paulus Alexandrinus (which I reproduce below in the left column) is given, I found a marginal note (here on the right) in the hand of the late Professor F. C. Burkitt:—Burkitt's opinion obviously was that, if we want to understand this list of the Acts, we must turn to astrological geography. This seemed a convincing suggestion and became even more convincing when I found how this passage had puzzled the commentators. Some of them felt that the writer meant to say ‘the whole oecumene’, but they could not explain why he mentions just these countries. What follows is intended to show that Burkitt's suggestion is sound.
