Greek philosophers
Strabo
Strabo was a Greek philosopher, historian and geographer. He was born in 64 BC (Amaseia in Pontus) and died sometime between 19 and 24 AD. He is best known as the author of the Geographica, the most extensive surviving geographical work of antiquity.
Strabo studied in Rome under Xenarchus, but later inclined towards Stoic philosophy. At the same time, he claimed that there was no one among geographers who had travelled more countries than he had.
His Geographica is the only ancient geographical work whose text has survived to this day. This work is 17 volumes long and was intended as a practical guide for Roman statesmen, military leaders, provincial officials and merchants. The work also includes an account of the evolution of the Earth's surface, the dimensions of the Earth and much more. The 15 volumes contain descriptions of the various countries and regions.
Among the best appreciated volumes are Asia Minor, Egypt and Libya, which the author wrote based on his own knowledge. However, the quality and credibility of the facts in the other volumes varies widely. There are also many factual errors, such as Ireland being described as the northernmost inhabited country, or Africa being smaller in area than Europe.
The basic ideas of this work are taken from Erastothenes, Polybius of Megalopolis, and Poseidonius of Apamea. It was Poseidonius whom he described as the most learned philosopher of his time.
