Ptolemy I Soter

Ptolemy I Soter I (Ancient Greek: Πτολεμαῖος Σωτήρ, Ptolemaĩos Sōtḗr, i.e. Ptolemy (pronounced /ˈtɒləmi/) the Savior), also known as Ptolemy Lagides, c. 367 BC – c. 283 BC, was a Macedonian general under Alexander the Great, who became ruler of Egypt (323–283 BC) and founder of the Ptolemaic Kingdom and dynasty. In 305/4 BC he demanded the title of pharaoh. His successors ruled Egypt for approximately three centuries, turning Egypt into a Hellenistic kingdom and a center of Greek culture.

Like all Macedonian nobles, Ptolemy I Soter claimed descent from Heracles, the mythical founder of the Argead dynasty that ruled Macedon. Ptolemy's mother was Arsinoe of Macedon, and, while his father is unknown, ancient sources variously describe him either as the son of Lagus, a Macedonian nobleman, or as an illegitimate son of Philip II of Macedon (which, if true, would have made Ptolemy the half-brother of Alexander), but it is possible that this is a later myth fabricated to glorify the Ptolemaic dynasty. Ptolemy was one of Alexander's most trusted generals, and was among the seven somatophylakes (bodyguards) attached to his person. He was a few years older than Alexander, and had been his intimate friend since childhood.

Ptolemy

Claudius Ptolemy (/ˈtɒləmi/; Greek: Κλαύδιος Πτολεμαῖος, Klaúdios Ptolemaîos, [kláwdios ptolɛmɛ́ːos]; Latin: Claudius Ptolemaeus; c. AD 100 – c. 170) was a Greco-Egyptian writer, known as a mathematician, astronomer, geographer, astrologer, and poet of a single epigram in the Greek Anthology. He lived in the city of Alexandria in the Roman province of Egypt, wrote in Koine Greek, and held Roman citizenship. Beyond that, few reliable details of his life are known. His birthplace has been given as Ptolemais Hermiou in the Thebaid in an uncorroborated statement by the 14th-century astronomer Theodore Meliteniotes. This is a very late attestation, however, and there is no other 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, three of which were of continuing importance to later Byzantine, Islamic and European science. The first is the astronomical treatise now known as the Almagest, although it was originally entitled the "Mathematical Treatise" (Μαθηματικὴ Σύνταξις, Mathēmatikē Syntaxis) and then known as the "Great Treatise" (Ἡ Μεγάλη Σύνταξις, Ē Megálē Syntaxis). The second is the Geography, which is a thorough discussion of the geographic knowledge of the Greco-Roman world. This manuscript was used by Christopher Columbus as the map for his westward-bound path to Asia, in which he discovered the hitherto unknown lands of the Americas. The third is the astrological treatise in which he attempted to adapt horoscopic astrology to the Aristotelian natural philosophy of his day. This is sometimes known as the Apotelesmatika (Ἀποτελεσματικά) but more commonly known as the Tetrabiblos from the Greek (Τετράβιβλος) meaning "Four Books" or by the Latin Quadripartitum.

Ptolemy (general)

Ptolemy (Greek: Πτολεμαῖος); died 309 BC) was a nephew of Antigonus, and who served as a general to Alexander the Great (338–323 BC) who afterwards became king of Asia.

He is first mentioned as being present with his uncle at the siege of Nora in 320 BC, when he was given up to Eumenes as a hostage for the safety of the latter during a conference with Antigonus. At a later period we find him entrusted by his uncle with commands of importance. Thus in 315 BC, when Antigonus was preparing to oppose the formidable coalition organized against him, he placed Ptolemy at the head of the army which was destined to carry on operations in Anatolia against the generals of Cassander.

The young general successfully carried out his mission, thereby relieving Amisus, which was besieged by Asclepiodorus, and recovered the whole satrapy of Cappadocia; after which he advanced into Bithynia, compelling king Zipoites to join his alliance. Upon his approach and occupation of Ionia, Seleucus withdrew from that territory.

Ptolemy (name)

The name Ptolemy or Ptolemaeus comes from the Greek Ptolemaios, which seems to mean warlike or son of war. There have been many people named Ptolemy or Ptolemaeus, the most famous of whom are the Greek-Egyptian astronomer Claudius Ptolemaeus, and the Macedonian founder and ruler of the Ptolemaic Kingdom in Egypt, Ptolemy I Soter. The following sections summarise the history of the name, some of the people named Ptolemy, and some of the other uses of this name.

Etymology and history

According to Georg Autenrieth the English name Ptolemy comes from the Ancient Greek name Πτολεμαῖος (Ptolemaios), "warlike" or "son of war". Autienrieth renders the meaning of the name to be an adjective from πτόλεμος (ptólemos), explained as a Homeric form of πόλεμος (pólemos), "war". A nephew of Antigonus I was called Polemaeus, the normal form of the adjective. Ptolemaios is first attested in Homer's Iliad and is the name of an Achaean warrior, son of Piraeus, father of Eurymedon.

The name Ptolemaios varied over the years from its roots in Ancient Greece, appearing in different languages in various forms and spellings. The original form, and some of the variants, are listed here in the languages relevant to the history of the name.
