Cyrene, sometimes anglicized as Kyrene, was an ancient Greek colony and Roman city near present-day Shahhat in northeastern Libya in North Africa. It was part of the Pentapolis, a group of five cities in the region and gave the area its name Cyrenaica.
 | Founded in the 7th century B.C., Cyrene was one of the principal cities in the Hellenic world. |
 | UNESCO added the site to its World Heritage List in 1992. “A thousand years of history is written into its ruins,” it said. The city was attributed to Apollo and the legendary etymon Cyrene by the Greeks but it was probably colonized by settlers from Thera (modern Santorini) in the late seventh century BC. |  |
It was initially ruled by a dynasty of monarchs called the Battiads, who grew rich from the export of horses and silphium.
 The ruins of Cyrene survived Libya’s 2011 revolution and a decade of lawlessness but now face looters. | |  |
Silphium (silphion or laser) was an ancient miracle plant, highly prized by Greeks and Romans as a spice, medicine, and highly effective contraceptive. When Rome assumed control of Cyrene, private contractors heavily over-harvested the wild rootstocks to maximize profits.
 | Silphium is claimed to have become extinct in Roman times during the reign of Nero. Silphium had an extremely small growing range, about 125 by 35 miles (201 by 56 km), in the southern steppe of Cyrenaica. Extremely valuable, overharvesting has long been cited as the primary factor that led to its extinction. It could not be cultivated from seed but instead only asexually through their roots. The plant may have been a Roman hybrid. | |
