^Strabo, Geographica, book 2, chapter 5, start of paragraph 8: Ὁ μὲν οὖν Μασσαλιώτης Πυθέας τὰ περὶ Θούλην τὴν βορειοτάτην τῶν Βρεττανίδων ὕστατα λέγει, παρ' οἷς ὁ αὐτός ἐστι τῷ ἀρκτικῷ ὁ θερινὸς τροπικὸς κύκλος· "
Pytheas of
Massalia therefore chooses the furthest regions around
Thule, [which is] the most northern of the lands around Britain, around which the "summer turning circle" [= the line of celestial latitude where the sun turns at midsummer] is the same as the
Arctic Circle.", which may refer to the sun being
circumpolar at midsummer. Strabo 1.4.2: ἥν φησι Πυθέας ἀπὸ μὲν τῆς Βρεττανικῆς ἓξ ἡμερῶν πλοῦν ἀπέχειν πρὸς ἄρκτον, ἐγγὺς δ᾽ εἶναι τῆς πεπηγυίας θαλάττης : "[Thule] which Pytheas says is a six days’ sail north of Britain, and is near the frozen sea."
