Note 627 — Chapter II
W. (William) Falconer translation
The Arctic Circles of the ancients were not the same as ours, but varied for every latitude. Aristotle limited the temperate zone to those countries which had the constellation of the crown in their Arctic Circle, the brilliant star of that constellation in his time had a northern declination of about 36° 30´, consequently he did not reckon that the temperate zone reached farther north or south than 53° and a half. We shall see that Strabo adopted much the same opinion, fixing the northern bounds of the habitable earth at 54° 25′ 42″. Gosselin.
