Timosthenes

In the 280s–270s BCE, Timosthenes served as the admiral and chief pilot of the Ptolemaic navy of King Ptolemy II Philadelphus of Egypt. He wrote a periplus (a book of sailing directions) in ten books (now lost), and was much admired and cited by other geographers such as Eratosthenes and Strabo.[1] Indeed, Marcian of Heraclea went so far as to accuse Eratosthenes' Geographica of being nothing but the wholesale plagiarism of Timosthenes work.[2] Strabo says only that Eratosthenes preferred Timosthenes "above any other writer, though he often decides even against him."[3]

According to the later Greek geographer Agathemerus (fl.250 CE), Timosthenes of Rhodes developed a system of twelve winds by adding four winds to the classical eight, introducing the complete 12-point Classical compass winds of Classical Antiquity.[4] Timosthenes was arguably the first of the Greek geographers to use the winds for geographic orientation, rather than merely as meteorological phenomena.

Strabo reports that Timosthenes wrote a "Pythian mood" (nomos) for a musical contest at the Pythian games at Delphi. Timosthenes's strain (melos), accompanied by flute and cithara, celebrated the contest between Apollo and the serpent Python.[5]

Mount Timosthenes in Antarctica is named after him. .
