Timosthenes

Timosthenes of Rhodes (Greek: ) (fl. 270 BCE) was a Greek navigator, geographer and admiral in Ptolemaic navy. He is credited with inventing the system of twelve winds that became known as the Greek 12-wind rose.

==Career== 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. Indeed, Marcian of Heraclea went so far as to accuse Eratosthenes' Geographica of being nothing but the wholesale plagiarism of Timosthenes work. Strabo says only that Eratosthenes preferred Timosthenes "above any other writer, though he often decides even against him."
