Claudius Ptolemy ( /ˈtɒləmi/; Greek: Κλαύδιος Πτολεμαῖος, Klaudios Ptolemaios; Latin: Claudius Ptolemaeus; c. AD 90 – c. AD 168), was a Greek-Roman citizen of Egypt who wrote in Greek. He was a mathematician, astronomer, geographer, astrologer, and poet of a single epigram in the Greek Anthology. He lived in Egypt under Roman rule, and is believed to have been born in the town of Ptolemais Hermiou in the Thebaid. This theory, proposed by Theodore Meliteniotes, could be correct, but it is late (ca. 1360) and unsupported. There is no reason to suppose that he ever lived anywhere else than Alexandria, where he died around AD 168.
Ptolemy was the author of several scientific treatises, at least three of which were of continuing importance to later Islamic and European science. The first is the astronomical treatise now known as the Almagest (in Greek, Ἡ Μεγάλη Σύνταξις, "The Great Treatise", originally Μαθηματικὴ Σύνταξις, "Mathematical Treatise"). The second is the Geography, which is a thorough discussion of the geographic knowledge of the Greco-Roman world. The third is the astrological treatise known sometimes in Greek as the Apotelesmatika (Ἀποτελεσματικά), more commonly in Greek as the Tetrabiblos (Τετράβιβλος "Four books"), and in Latin as the Quadripartitum (or four books) in which he attempted to adapt horoscopic astrology to the Aristotelian natural philosophy of his day.
Ptolemy V Epiphanes (Ancient Greek: Πτολεμαῖος Ἐπιφανής, Ptolemaĩos Epiphanḗs, reigned 204–181 BC), son of Ptolemy IV Philopator and Arsinoe III of Egypt, was the fifth ruler of the Ptolemaic dynasty. He became ruler at the age of five, and under a series of regents the kingdom was paralyzed.
Ptolemy Epiphanes was only a small boy when his father, Ptolemy Philopator, died. The two leading favorites of Philopator, Agathocles and Sosibius, fearing that Arsinoe would secure the regency had her murdered before she heard of her husband's death, which secured the regency for themselves. In 202 BC however Tlepolemus, the general in charge of Pelusium, put himself at the head of a revolt. Once Epiphanes was in the hands of Tlepolemus he was persuaded to give a sign that the killers of his mother should be killed. According to Bevan the child king's consent was given more from fear than anything else and Agathocles along with several of his supporters being killed by the Alexandrian mob.
Antiochus III the Great and Philip V of Macedon made a pact to divide the Ptolemaic possessions overseas. Philip seized several islands and places in Caria and Thrace, whilst the Battle of Panium (198 BC) definitely transferred Coele-Syria, including Judea, from the Ptolemies to the Seleucids.
