Ptolemy II Philadelphus in the context of "Greek Old Testament"

The Lighthouse of Alexandria, sometimes called the Pharos of Alexandria, was a lighthouse built by the Ptolemaic Kingdom of Ancient Egypt, during the reign of Ptolemy II Philadelphus (280–247 BC). It has been estimated to have been at least 100 metres (330 ft) in overall height. One of the Seven Wonders of the Ancient World, for many centuries it was one of the tallest man-made structures in the world.

The lighthouse was severely damaged by three earthquakes between 956 and 1303 AD and became an abandoned ruin. It was the third-longest surviving ancient wonder, after the Mausoleum at Halicarnassus and the extant Great Pyramid of Giza, surviving in part until 1480, when the last of its remnant stones were used to build the Citadel of Qaitbay on the site.

The Library of Alexandria in Alexandria, Egypt, was one of the largest and most significant libraries of the ancient world. The library was part of a larger research institution called the Mouseion, which was dedicated to the Muses, the nine goddesses of the arts. The idea of a universal library in Alexandria may have been proposed by Demetrius of Phalerum, an exiled Athenian statesman living in Alexandria, to Ptolemy I Soter, who may have established plans for the library, but the library itself was probably not built until the reign of his son Ptolemy II Philadelphus. The library quickly acquired many papyrus scrolls, owing largely to the Ptolemaic kings' aggressive and well-funded policies for procuring texts. It is unknown precisely how many scrolls were housed at any given time, but estimates range from 40,000 to 400,000 at its height.

Alexandria came to be regarded as the capital of knowledge and learning, in part because of the Great Library. Many important and influential scholars worked at the Library during the third and second centuries BC, including: Zenodotus of Ephesus, who worked towards standardizing the works of Homer; Callimachus, who wrote the Pinakes, sometimes considered the world's first library catalog; Apollonius of Rhodes, who composed the epic poem the Argonautica; Eratosthenes of Cyrene, who calculated the circumference of the earth within a few hundred kilometers of accuracy; Hero of Alexandria, who invented the first recorded steam engine; Aristophanes of Byzantium, who invented the system of Greek diacritics and was the first to divide poetic texts into lines; and Aristarchus of Samothrace, who produced the definitive texts of the Homeric poems as well as extensive commentaries on them. During the reign of Ptolemy III Euergetes, a daughter library was established in the Serapeum, a temple to the Greco-Egyptian god Serapis.

The Septuagint (/ˈsɛptjuədʒɪnt/ SEP-tew-ə-jint), sometimes referred to as the Greek Old Testament or The Translation of the Seventy (Koine Greek: Ἡ μετάφρασις τῶν Ἑβδομήκοντα, romanized: Hē metáphrasis tôn Hebdomḗkonta), and abbreviated as LXX, is the earliest extant Greek translation of the Hebrew Bible from the original Biblical Hebrew. The full Greek title derives from the story recorded in the Letter of Aristeas to Philocrates that "the laws of the Jews" were translated into the Greek language at the request of Ptolemy II Philadelphus (285–247 BC) by seventy-two Hebrew translators—six from each of the Twelve Tribes of Israel—though this story is considered to be pseudepigraphical by some scholars.

Biblical scholars agree that the first five books of the Hebrew Bible were translated from Biblical Hebrew into Koine Greek by Jews living in the Ptolemaic Kingdom, centred on the large community in Alexandria, probably in the early or middle part of the 3rd century BC. The remaining books were presumably translated in the 2nd century BC. Some targums translating or paraphrasing the Bible into Aramaic were also made during the Second Temple period.

The Mouseion of Alexandria (Ancient Greek: Μουσεῖον τῆς Ἀλεξανδρείας; Latin: Musaeum Alexandrinum), which arguably included the Library of Alexandria, was an institution said to have been founded by Ptolemy I Soter and his son Ptolemy II Philadelphus. Originally, the word mouseion meant any place that was dedicated to the Muses, often related to the study of music or poetry, but later associated with sites of learning such as Plato's Academy and Aristotle's Lyceum.

The Ptolemies reputedly established their Mouseion and Library with the intention of bringing together some of the best scholars of the Hellenistic world and to collect all the books known at the time. Although it did not imply a collection of works of art, the word mouseion is the root for the modern usage of the word museum.

Sopater of Paphos (Ancient Greek: Σώπατρος ὁ Πάφιος) was a 3rd-century BC parodist and playwright. Atheneus reports on his lifetime in his Deipnosophistae. According to Atheneus, Sopater lived in the time of Alexander the Great, and "was still alive in the reign of the second king of Egypt". After Ptolemy II Philadelphus (308-246 BC) succeeded his father on the throne of Egypt in 283/2 BC, and considering that the work of Sopater was likely composed after Ptolemy II's victory against the Gauls in 270 BC and makes reference to him, scholars place Sopater in the last thirty years of the 4th and the first half of the 3rd century BC. He is believed to have spent a significant part of his life spent in Alexandria.

A few of Sopater's works are known to us through Atheneus' Deipnosophistae, these are: Bacchus, Eubulotheombrutus, Pylaeus and Phacis are described in the ancient source as dramas. Other sources like the 10th century Byzantine encyclopedia Suidas count nine works in total: Hippolytus, Physiologus, Silpho, Cnidia, Nekia, Pylaeus, Orestes, Phacis and Bacchus. Sopatros, in addition to the indicative of his Paphos descent, is called a parodist and a phlyax writer in Athenaeus, and a comedian in Suidas.

Callimachus (/kəˈlɪməkəs/; Ancient Greek: Καλλίμαχος, romanized: Kallimachos; c. 310 – c. 240 BC) was an ancient Greek poet, scholar, and librarian who was active in Alexandria during the 3rd century BC. A representative of Ancient Greek literature of the Hellenistic period, he wrote over 800 literary works, most of which do not survive, in a wide variety of genres. He espoused an aesthetic philosophy, known as Callimacheanism, which exerted a strong influence on the poets of the Roman Empire and, through them, on all subsequent Western literature.

Born into a prominent family in the Greek city of Cyrene in modern-day Libya, he was educated in Alexandria, the capital of the Ptolemaic kings of Egypt. After working as a schoolteacher in the city, he came under the patronage of King Ptolemy II Philadelphus and was employed at the Library of Alexandria where he compiled the Pinakes, a comprehensive catalogue of all Greek literature. He is believed to have lived into the reign of Ptolemy III Euergetes.

Ptolemy III Euergetes (Greek: Πτολεμαῖος Εὐεργέτης, romanized: Ptolemaîos Euergétēs, "Ptolemy the Benefactor"; c. 280 – November/December 222 BC) was the third pharaoh of the Ptolemaic dynasty in Egypt from 246 to 222 BC. The Ptolemaic Kingdom reached the height of its military and economic power during his kingship, as initiated by his father Ptolemy II Philadelphus.

Ptolemy III was the eldest son of Ptolemy II and Arsinoe I. When Ptolemy III was young, his mother was disgraced and he was removed from the succession. He was restored as heir to the throne in the late 250s BC and succeeded his father as king without issue in 246 BC. On his succession, Ptolemy III married Berenice II, reigning queen of Cyrenaica, thereby bringing her territory into the Ptolemaic realm. In the Third Syrian War (246–241 BC), Ptolemy III invaded the Seleucid empire and won a near total victory, but was forced to abandon the campaign as a result of an uprising in Egypt. In the aftermath of this rebellion, Ptolemy forged a closer bond with the Egyptian priestly elite, which was codified in the Canopus decree of 238 BC and set a trend for Ptolemaic power in Egypt for the rest of the dynasty. In the Aegean, Ptolemy III suffered a major setback when his fleet was defeated by the Antigonids at the Battle of Andros around 246 BC, but he continued to offer financial support to their opponents in mainland Greece for the rest of his reign. At his death, Ptolemy III was succeeded by his eldest son, Ptolemy IV.
