Page "Pytheas" Paragraph 5

Pytheas described his travels in a work that has not survived ; only excerpts remain, quoted or paraphrased by later authors, most familiarly in Strabo's Geographica, Pliny's Natural History and passages in Diodorus of Sicily's history.

Two late writers give titles: the astronomical author Geminus of Rhodes mentions ( ta peri tou Okeanou ), literally " things about the Ocean ", sometimes translated as " Description of the Ocean ", " On the Ocean " or " Ocean ;" Marcianus, the scholiast on Apollonius of Rhodes, mentions a ( periodos gēs ), a " trip around the earth " or ( periplous ), " sail around.
