I am having trouble translating this to make sense, can someone take a shot at it for me? Asia est ista non magna illa scilicet quae dicitur tertia pars mundi, sed quaedam prouincia ubi erant septem ciuitates, & septem ecclesie.
That Asia is not that large one, ie the one which is said to be a third part of the world, but a province where there were seven cities and seven churches. He will be talking about the Roman province of Asia.
Just a small detail: "third part of the world" = one-third of the world. Both the presence and ending of ecclesie suggest a mediaeval provenance. At that time, of course, they only knew of three continents.
