Ptolemy I Soter
Ptolemy I Soter(" Ptolemaîos SōtḗrPtolemy the Savior"; c. 367 BC – January 282 BC) was a companion and historian of Alexander the Great of the Kingdom of Macedon in northern Greece who became ruler of Egypt, part of Alexander's former empire.
Ptolemy was pharaoh of Ptolemaic Egypt from 305/304 BC to his death.
He was the founder of the Ptolemaic dynasty which ruled Egypt until the death of Cleopatra in 30 BC, turning the country into a Hellenistic kingdom and Alexandria into a center of Greek culture.
Ptolemy I was the son of Arsinoe of Macedon by either her husband Lagus or Philip II of Macedon, the father of Alexander.
Ptolemy was one of Alexander's most trusted companions and military officers.
After the death of Alexander in 323 BC, Ptolemy retrieved his body as it was en route to be buried in Macedon, placing it in Memphis instead, where it was later moved to Alexandria in a new tomb.
Afterwards he joined a coalition against Perdiccas, the royal regent over Philip III of Macedon.
The latter invaded Egypt but was assassinated by his own officers in 320 BC, allowing Ptolemy I to consolidate his control over the country.
After a series of wars between Alexander's successors, Ptolemy gained a claim to Judea in southern Syria which was disputed with the Syrian king Seleucus I Nicator, his former ally.
He also took control of Cyprus and Cyrenaica, the latter of which was placed under the control of Ptolemy's stepson Magas.
Ptolemy I may have married
Thaïs, his mistress during the life of Alexander; he is known to have married the Persian noblewoman Artakama on Alexander's orders.
He later married Eurydice, daughter of the Macedonian regent Antipater; their sons Ptolemy Keraunos and Meleager ruled in turn as kings of Macedon.
Ptolemy's final marriage was to Eurydice's cousin and lady- in- waiting, Berenice I. Ptolemy I died in 282 BC and was succeeded by his son with Berenice, Ptolemy II.
Philotera
Philotera( born 315/309 BC- probably after 282 BC and before 268 BC) was a Greek Macedonian noblewoman and a Greek Egyptian princess of the Ptolemaic dynasty.
Philotera was the daughter of Ptolemy I Soter and Berenice I of Egypt.
She had one older sister, Arsinoe II, and a younger brother, the future Pharaoh Ptolemy II Philadelphus.
From her parents' previous marriages, Philotera had various half- maternal and half- paternal siblings.
Little is known of her life.
Philotera died sometime after the accession of Ptolemy II to the Ptolemaic throne and before Arsinoe II died.
The fact that Philotera died before her sister did is demonstrated by a hymn written by Callimachus on the death of Arsinoe II.
After Philotera died, Ptolemy II deified her as a goddess.
Ptolemy II erected a temple in her honor in Alexandria.
Greeks and Egyptians worshipped her along with Arsinoe II, and Ptolemy II created a religious cult in her honour.
Ptolemy II also founded a port town in the Red Sea called Philotera, which is modern Safaga.
