Strabo 3.1.5
ταῦτα μὲν οὖν οὕτως ἔχειν ἐγχωρεῖ καὶ δεῖ πιστεύειν: ἃ δὲ τοῖς πολλοῖς καὶ χυδαίοις ὁμοίως εἴρηκεν, οὐ πάνυ. λέγειν γὰρ δή φησι Ποσειδώνιος τοὺς πολλοὺς μείζω δύνειν τὸν ἥλιον ἐν τῇ παρωκεανίτιδι καὶ μετὰ ψόφου παραπλησίως ὡσανεὶ σίζοντος τοῦ πελάγους κατὰ σβέσιν αὐτοῦ διὰ τὸ ἐμπίπτειν εἰς τὸν βυθόν
Now these assertions of Artemidorus are allowable, and we should believe them; but the stories which he has told in agreement with the common crowd of people are by no means to be believed. For example, it is a general saying among the people, according to Poseidonius, that in the regions along the coast of the ocean the sun is larger when it sets, and that it sets with a noise much as if the sea were sizzling to extinguish it because of its falling into the depths.
