who built the port city of berenice on the red sea
Berenice Troglodytica It was founded in 275 BC by Ptolemy II Philadelphus (285â€“246 BC), who named it after his mother, Berenice I of Egypt.[3] Troglodytica refers to the aboriginal people of the region, the "Troglodytai" or "cave dwellers". Although the name is attested by several ancient writers, the more ancient Ptolemaic inscriptions read Trogodytai (which G.W.B. Huntingford has speculated could be related to the same root as Tuareg). It is possible that later copyists confused this name with the more common term Troglodytai.
