Aristippus of Cyrene

from THE ARCHITECTURE, by MARCUS VITRUVIUS POLLIO.
BOOK THE SIXTH, INTRODUCTION.

ARISTIPPUS, the Socratic philosopher, shipwrecked on the coast of Rhodes, perceiving some geometrical diagrams thereon, is reported to have exclaimed to his companions, " Be of good courage, I see marks of civilization" and straightway making for the city of Rhodes, he arrived at the Gymnasium; where, disputing on philosophical subjects, he obtained such honours, that he not only provided for himself, but furnished clothing and food to his companions. When his companions had completed their arrangements for returning home, and asked what message he wished to send to his friends, he desired them to say that the possessions and provision to be made for children should be those which can be preserved in case of shipwreck; inasmuch as those things are the real supports of life which the chances of fortune, the changes of public affairs, and the devastation of war, cannot injure.

Hic sunt Garamantes

"Satellites and aerial photographs have revealed evidence of over a hundred fortified farms, villages, and towns - many with castle-like structures - in the southwestern deserts of Libya. These structures date back to between 1 and 500 C.E., meaning they predate the rise of Islam. ...
Archaeologists from the University of Leicester have used all this aerial data to identify as much as they can about the so-called Garamantes people, who are otherwise known purely through Greek and Roman sources. They've already discovered "the mud brick remains of the castle-like complexes, with walls still standing up to four metres high, along with traces of dwellings, cairn cemeteries, associated field systems, wells and sophisticated irrigation systems."

Garamantes

Garamantes lived in fertile areas of Sahara, corresponding to the southwestern Libya, which had not always been a desert. In a period lasting from about 10,000 to 6,000 before current era, the country was like a savanna, with some perennial lakes. During the sixth millennium, several great droughts forced people to abandon the region. The lakes disappeared, leaving large fields of salt, one of the main articles of future Garamantian trade.
