Ptolemy II Philadelphus

Ptolemy II Philadelphus (Greek: Πτολεμαῖος Φιλάδελφος, Ptolemaîos Philádelphos, 309–246 BCE) was the king of Ptolemaic Egypt from 283 to 246 BCE. He was the son of the founder of the Ptolemaic kingdom Ptolemy I Soter and Berenice, and was educated by Philitas of Cos. He had two half-brothers, Ptolemy Keraunos and Meleager, who both became kings of Macedonia (in 281 BCE and 279 BCE respectively), and who both died in the Gallic invasion of 280–279 BCE. Ptolemy was first married to Arsinoë I, daughter of Lysimachus, who was the mother of his legitimate children; after her repudiation he married his full sister Arsinoë II, the widow of Lysimachus.

During Ptolemy's reign, the material and literary splendour of the Alexandrian court was at its height. He promoted the Museum and Library of Alexandria, and he erected a commemorative stele, the Great Mendes Stela.

Reign

Ptolemy II began his reign as co-regent with his father Ptolemy I from c. 285 BCE to c. 283 BCE, and maintained a splendid court in Alexandria.

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.

Old Testament

The Old Testament is the first section of the Christian Bible, based primarily upon the Hebrew Bible, a collection of religious writings by ancient Israelites. It is the counterpart to the New Testament, the second portion of the Christian Bible. The Old Testament canon varies between Christian Churches; Protestants and Latter-Day Saints accept only the books found in the canon of the Hebrew Bible, dividing them into 39 books, while the Catholic, Eastern Orthodox, and Oriental Orthodox Churches accept somewhat larger collections of writings.

The Old Testament consists of many distinct books written, compiled, and edited by various authors over a period of centuries. It is not entirely clear at what point the parameters of the Hebrew Bible, the basis for the Christian Old Testament, were fixed. Some scholars have opined that the canon of the Hebrew Bible was established already by about the 3rd century BC, or even later.

The books of the Old Testament can be broadly divided into several sections: 1) the first five books or Pentateuch (Torah); 2) the history books telling the history of the Israelites, from their conquest of Canaan to their defeat and exile in Babylon; 3) the poetic and "Wisdom" books dealing, in various forms, with questions of good and evil in the world; 4) and the books of the biblical prophets, warning of the consequences of turning away from God.

Alexander the Great

Alexander III of Macedon (20/21 July 356 BC – 10/11 June 323 BC), commonly known as Alexander the Great (Greek: Ἀλέξανδρος ὁ Μέγας, Aléxandros ho Mégas [a.lék.san.dros ho mé.gas], from the Greek ἀλέξω (alexō) "defend" and ἀνδρ- (andr-), the stem of ἀνήρ (anēr) "man" and means "protector of men"), was a King (Basileus) of the Ancient Greek kingdom of Macedon and a member of the Argead dynasty, an ancient Greek royal house. Born in Pella in 356 BC, Alexander succeeded his father, Philip II, to the throne at the age of twenty. He spent most of his ruling years on an unprecedented military campaign through Asia and northeast Africa, and by the age of thirty he had created one of the largest empires of the ancient world, stretching from Greece to Egypt into northwest India and modern-day Pakistan. He was undefeated in battle and is widely considered one of history's most successful military commanders.

During his youth, Alexander was tutored by the philosopher Aristotle until the age of 16. After Philip's assassination in 336 BC, Alexander succeeded his father to the throne and inherited a strong kingdom and an experienced army. Alexander was awarded the generalship of Greece and used this authority to launch his father's Panhellenic project to lead the Greeks in the conquest of Persia. In 334 BC, he invaded the Achaemenid Empire, ruled Asia Minor, and began a series of campaigns that lasted ten years. Alexander broke the power of Persia in a series of decisive battles, most notably the battles of Issus and Gaugamela. He subsequently overthrew the Persian King Darius III and conquered the Achaemenid Empire in its entirety. At that point, his empire stretched from the Adriatic Sea to the Indus River.

Apostolic Fathers

The Apostolic Fathers is a term used to describe a group of Early Christian writings produced in the late 1st century and the first half of the 2nd century. These writings, though popular in Early Christianity, were ultimately not part of the New Testament once it reached its final form. Many of the writings derive from the same time period and geographical location as other works of early Christian literature that did come to be part of the final form of the New Testament, and some of the writings found among the "Apostolic Fathers" seem to have been just as highly regarded as some of the writings (that remained) in the New Testament.
