Apeiron

Apeiron (ἄπειρον) is a Greek word meaning "(that which is) unlimited," "boundless", "infinite", or "indefinite" from ἀ- a-, "without" and πεῖραρ peirar, "end, limit", "boundary", the Ionic Greek form of πέρας peras, "end, limit, boundary"

The apeiron is central to the cosmological theory created by Anaximander, a 6th-century BC pre-Socratic Greek philosopher whose work is mostly lost. From the few existing fragments, we learn that he believed the beginning or ultimate reality (arche) is eternal and infinite, or boundless (apeiron), subject to neither old age nor decay, which perpetually yields fresh materials from which everything we can perceive is derived. Apeiron generated the opposites, hot-cold, wet-dry etc., which acted on the creation of the world. Everything is generated from apeiron and then it is destroyed by going back to apeiron, according to necessity. He believed that infinite worlds are generated from apeiron and then they are destroyed there again.

Hippasus

Hippasus of Metapontum (5th century BC), was a Pythagorean philosopher. Little is known about his life or his beliefs, but he is sometimes credited with the discovery of the existence of irrational numbers. The discovery of irrational numbers is said to have been shocking to the Pythagoreans, and Hippasus is supposed to have drowned at sea, apparently as a punishment from the gods for divulging this. However, the few ancient sources which describe this story either do not mention Hippasus by name (e.g. Pappus) or alternatively tell that Hippasus drowned because he revealed how to construct a dodecahedron inside a sphere. The discovery of irrationality is not specifically ascribed to Hippasus by any ancient writer. Some modern scholars though have suggested that he discovered the irrationality of √2, which is believed to have been discovered around the time that he lived.

Diogenes and Alexander

Thereupon many statesmen and philosophers came to Alexander with their congratulations, and he expected that Diogenes of Sinope also, who was tarrying in Corinth, would do likewise. But since that philosopher took not the slightest notice of Alexander, and continued to enjoy his leisure in the suburb Craneion, Alexander went in person to see him; and he found him lying in the sun. Diogenes raised himself up a little when he saw so many people coming towards him, and fixed his eyes upon Alexander. And when that monarch addressed him with greetings, and asked if he wanted anything, "Yes," said Diogenes, "stand a little out of my sun." It is said that Alexander was so struck by this, and admired so much the haughtiness and grandeur of the man who had nothing but scorn for him, that he said to his followers, who were laughing and jesting about the philosopher as they went away, "But truly, if I were not Alexander, I would be Diogenes."

Diotima

Diotima of Mantinea was a philosopher and priestess circa 440 B.C.E. who plays an important role in Plato's Symposium. Her ideas are the origin of the concept of  Platonic love.

The name Diotima means Zeus Honor, either in the active sense of a woman who honors Zeus, or in the passive sense of a woman honored by Zeus.

Galen of Pergamon

Aelius Galenus or Claudius Galenus ( Greek: Κλαύδιος Γαληνός; September 129 AD – c. 200/c. 216), and better known as Galen of Pergamon  was a prominent Greek physician, surgeon and philosopher in the Roman Empire. Arguably the most accomplished of all medical researchers of antiquity, Galen influenced the development of various scientific disciplines, including anatomy, physiology, pathology, pharmacology, and neurology, as well as philosophy and logic.
 Galen's understanding of anatomy and medicine was principally influenced by the then-current theory of humorism (also known as the four humors – black bile, yellow bile, blood, and phlegm), as advanced by ancient Greek physicians such as Hippocrates. His theories dominated and influenced Western medical science for more than 1,300 years. His anatomical reports, based mainly on dissection of monkeys, especially the Barbary macaque, and pigs, remained uncontested until 1543, when printed descriptions and illustrations of human dissections were published in the seminal work De humani corporis fabrica by Andreas Vesalius where Galen's physiological theory was accommodated to these new observations. Galen's theory of the physiology of the circulatory system endured until 1628, when William Harvey published his treatise entitled De motu cordis, in which he established that blood circulates, with the heart acting as a pump. Medical students continued to study Galen's writings until well into the 19th century.

…Galen's influence was so great that when dissections discovered anomalies compared with Galen's anatomy, the physicians often tried to fit these into the Galenic system. An example of this is Mondino de Liuzzi, who describes rudimentary blood circulation in his writings but still asserts that the left ventricle should contain air. Some cited these changes as proof that human anatomy had changed since the time of Galen…

Epimenides paradox

Epimenides of Knossos (Crete) was a semi-mythical 7th or 6th century BC Greek seer and philosopher-poet.
While tending his father's sheep, Epimenides is said to have fallen asleep for fifty-seven years in a Cretan cave sacred to Zeus, after which he reportedly awoke with the gift of prophecy (Diogenes Laërtius i. 109–115). Plutarch writes that Epimenides purified Athens after the pollution brought by the Alcmeonidae, and that the seer's expertise in sacrifices and reform of funeral practices were of great help to Solon in his reform of the Athenian state. The only reward he would accept was a branch of the sacred olive, and a promise of perpetual friendship between Athens and Knossus (Plutarch, Life of Solon, 12; Aristotle, Ath. Pol. 1).

Paradox
Epimenides was a 6th-century BC philosopher and religious prophet who, against the general sentiment of Crete, proposed that Zeus was immortal, as in the following poem:

They fashioned a tomb for thee, O holy and high oneThe Cretans, always liars, evil beasts, idle bellies!But thou art not dead: thou livest and abidest forever,For in thee we live and move and have our being. (Epimenides, Cretica)

Epimenides paradox is as follows: "Epimenides the Cretan says, 'that all the Cretans are liars,' but Epimenides is himself a Cretan; therefore he is himself a liar. But if he be a liar, what he says is untrue, and consequently the Cretans are veracious; but Epimenides is a Cretan, and therefore what he says is true; saying the Cretans are liars, Epimenides is himself a liar, and what he says is untrue. Thus we may go on alternately proving that Epimenides and the Cretans are truthful and untruthful.

Painting of Pheidippides as he gave word of the Greek victory over Persia at the Battle of Marathon to the people of Athens.Luc-Olivier Merson, 1869

Pheidippides is the central figure in a story that was the inspiration for a modern sporting event, the marathon race. Pheidippides is said to have run from Marathon to Athens to deliver news of a military victory against the Persians at the Battle of Marathon.The traditional story relates that Pheidippides (530 BC–490 BC), an Athenian herald or hemerodrome (translated as "day-runner""courier" "professional-running courier" or "day-long runner, was sent to Sparta to request help when the Persians landed at Marathon, Greece. He ran about 240 km (150 mi) in two days. He then ran the 40 km (25 mi) from the battlefield near Marathon to Athens to announce the Greek victory over Persia in the Battle of Marathon (490 BC) with the word nikomen "We win!", as stated by Lucian chairete, nikomen ("hail, we are the winners")and then collapsed and died.

Mother's of God icon with three hands

In the eighth century during the time of the Iconoclasts, Saint John of Damascus (December 4) was zealous in his veneration of holy icons. Because of this, he was slandered by the emperor and iconoclast Leo III the Isaurian (717-740), who informed the Damascus caliph that Saint John was committing treasonous acts against him. The caliph gave orders to cut off the hand of the monk and take it to the marketplace. Towards evening Saint John, having asked the caliph for the cut-off hand, put it to its joint and fell to the ground before the icon of the Mother of God. The monk begged Our Lady to heal the hand, which had written in defense of Orthodoxy. After long prayer he fell asleep and saw in a dream that the All-Pure Mother of God had turned to him promising him quick healing.
Before this the Mother of God bid him toil without fail with this hand. Having awakened from sleep, Saint John saw that his hand was unharmed. In thankfulness for this healing Saint John placed on the icon a hand fashioned of silver, from which the icon received its name “Of Three Hands.” (Some iconographers, in their ignorance, have mistakenly depicted the Most Holy Theotokos with three arms and three hands.) According to Tradition, Saint John wrote a hymn of thanksgiving to the Mother of God: “All of creation rejoices in You, O Full of Grace,” which appears in place of the hymn “It is Truly Meet” in the Liturgy of Saint Basil the Great.

Hylomorphism

Hylomorphism (or hylemorphism) is a philosophical theory developed by Aristotle, which conceives being (ousia) as a compound of matter and form.

The word is a 19th-century term formed from the Greek words ὕλη hyle, "wood, matter" and μορφή, morphē, "form."
Aristotle defines X's matter as "that out of which" X is made. For example, letters are the matter of syllables. Thus, "matter" is a relative term: an object counts as matter relative to something else. For example, clay is matter relative to a brick because a brick is made of clay, whereas bricks are matter relative to a brick house.Change is analyzed as a material transformation: matter is what undergoes a change of form. For example, consider a lump of bronze that's shaped into a statue. Bronze is the matter, and this matter loses one form (that of a lump) and gains a new form (that of a statue).According to Aristotle's theory of perception, we perceive an object by receiving its form with our sense organs. Thus, forms include complex qualia such as colors, textures, and flavors, not just shapes.Aristotle applies his theory of hylomorphism to living things. He defines a soul as that which makes a living thing alive. Life is a property of living things, just as knowledge and health are. Therefore, a soul is a form—that is, a specifying principle or cause—of a living thing. Furthermore, Aristotle says that a soul is related to its body as form to matter.
Hence, Aristotle argues, there is no problem in explaining the unity of body and soul, just as there is no problem in explaining the unity of wax and its shape. Just as a wax object consists of wax with a certain shape, so a living organism consists of a body with the property of life, which is its soul.

Daemon - J. Morisson's grave

James Douglas Morrison (December 8, 1943 – July 3, 1971) was an American singer, songwriter, and poet, best remembered as the lead singer of the Doors. Due to his poetic lyrics, distinctive voice, wild personality, performances, and the dramatic circumstances surrounding his life and early death, Morrison is regarded by both music critics and fans as one of the most iconic and influential frontmen in rock music history. Morrison was buried in Père Lachaise Cemetery in Paris, In the early-1990s, Morrison's father, after a consultation with E. Nicholas Genovese, Professor of Classics and Humanities, San Diego State University, placed a flat stone on the grave. The bronze plaque thereon bears the Greek inscription: ΚΑΤΑ ΤΟΝ ΔΑΙΜΟΝΑ ΕΑΥΤΟΥ, literally meaning "according to his own daemon, i.e., guiding spirit," to convey the sentiment "True to Himself."

In the ancient Greek religion, daimon designates not a specific class of divine beings, but a peculiar mode of activity: it is an occult power that drives humans forward or acts against them: since daimon is the veiled countenance of divine activity, every deity can act as daimon; a special knowledge of daimones is claimed by Pythagoreans; for Plato, daimon, is a spiritual being who watches over each individual, and is tantamount to a higher self, or an angel; whereas Plato is called ‘divine’ by Neoplatonists, Aristotle is regarded as daimonios, meaning ‘an intermediary to deities' – therefore Aristotle stands to Plato as an angel to a deity; for Proclus, daimones are the intermediary beings located between the celestial objects and the terrestrial inhabitants.

Mount Athos

An Orthodox spiritual centre since 1054, Mount Athos has enjoyed an autonomous statute since Byzantine times. The 'Holy Mountain', which is forbidden to women and children, is also a recognized artistic site. The layout of the monasteries (about 20 of which are presently inhabited by some 1,400 monks) had an influence as far afield as Russia, and its school of painting influenced the history of Orthodox art.

Ring of Gyges

The Ring of Gyges is a mythical magical artifact mentioned by the philosopher Plato in Book 2 of his Republic (2:359a–2:360d). It granted its owner the power to become invisible at will. Through the story of the ring, Republic considers whether an intelligent person would be moral if he did not have to fear being caught and punished for doing injustices.
