Hesiod Theogony.Pdf
Hesiod (8th or 7th c. BC, composed in Greek) The Homeric epics, the Iliad and the Odyssey, are probably slightly earlier than Hesiod’s two surviving poems, the Works and Days and the Theogony. Yet in many ways Hesiod is the more important author for the study of Greek mythology. While Homer treats cer- tain aspects of the saga of the Trojan War, he makes no attempt at treating myth more generally. He often includes short digressions and tantalizes us with hints of a broader tra- dition, but much of this remains obscure. Hesiod, by contrast, sought in his Theogony to give a connected account of the creation of the universe. For the study of myth he is im- portant precisely because his is the oldest surviving attempt to treat systematically the mythical tradition from the first gods down to the great heroes. Also unlike the legendary Homer, Hesiod is for us an historical figure and a real per- sonality. His Works and Days contains a great deal of autobiographical information, in- cluding his birthplace (Ascra in Boiotia), where his father had come from (Cyme in Asia Minor), and the name of his brother (Perses), with whom he had a dispute that was the inspiration for composing the Works and Days. His exact date cannot be determined with precision, but there is general agreement that he lived in the 8th century or perhaps the early 7th century BC. His life, therefore, was approximately contemporaneous with the beginning of alphabetic writing in the Greek world. Although we do not know whether Hesiod himself employed this new invention in composing his poems, we can be certain that it was soon used to record and pass them on. -

This is an educational package I have put future), meteorites, and “small bodies” in popular together to cover the so-called “small bodies” of the literature and music. solar system, which in general means asteroids and comets, although this also includes the small moons of Throughout 2020 there will be various comets that are the various planets as well as meteors, meteorites, and visible in our skies and various asteroids passing by Earth interplanetary dust. Although these objects may be -- some of which are already known, some of which “small” compared to the planets of our solar system, will be discovered “in the act” -- and there will also be they are nevertheless of high interest and importance various asteroids of the main asteroid belt that are visible for several reasons, including: as well as “occultations” of stars by various asteroids visible from certain locations on Earth’s surface. Ice a) they are believed to be the “leftovers” from the and Stone 2020 will make note of these occasions and formation of the solar system, so studying them provides appearances as they take place. The “Comet Resource valuable insights into our origins, including Earth and of Center” at the Earthrise web site contains information life on Earth, including ourselves; about the brighter comets that are visible in the sky at any given time and, for those who are interested, I will b) we have learned that this process isn’t over yet, and also occasionally share information about the goings-on that there are still objects out there that can impact in my life as I observe these comets. -

Pythios and Pythion: the Spread of a Cult Title J.K
Mediterranean Historical Review Vol. 22, No. 1, June 2007, pp. 57–69 Pythios and Pythion: The Spread of a Cult Title J.K. Davies The epithet Pythios/Pythion, unequivocally denoting the cult of Apollo of Delphi, came to have a very widespread distribution throughout the Greek world, comparable only to that of Zeus Olympios. Pre-Hellenistic attestations are summarily reported, showing concentrations (e.g., Attika, Argolis, Thessaly, Aegean islands, Krete), significant vacua (e.g., Boiotia, north-western Greece), and overlaps with the epithets Delphinios and Pythaieus. Likely periods and mechanisms of its spread are sketched, as are possible explanations (colonization, oracles, purification), though without overt preference for any one model of network-formation. Keywords: Apollo; Cult; Oracle; Purification; Distribution It is a cliche´ of scholarship that the terms Pythios and Pythion derive from Pytho, the earliest attested name for the cultic area later known as Delphoi,1 and that they came to refer unequivocally to Apollo as the principal god of the upper sanctuary there. They therefore belong among the ‘locational’ epithets of the god, parallel to Klarios or Didymeus, not among those derived from function or from association or identification with animals.2 As such, they pose a problem, for it was unusual for locational epithets to spread far beyond their primary sanctuary, still less to show such widespread attestation throughout much of the Greek-speaking world: Zeus Olympios provides perhaps the only true comparison, with even Eleusinian Demeter well behind. Their distribution therefore needs an explanation, and one which is couched not just in terms of geography or of the ‘profile’ of the god but also, and primarily, in terms of human needs and of the ways in which a specific cult could be transferred, or replicated/cloned, elsewhere. -
Insect Egg Size and Shape Evolve with Ecology but Not Developmental Rate Samuel H
ARTICLE https://doi.org/10.1038/s41586-019-1302-4 Insect egg size and shape evolve with ecology but not developmental rate Samuel H. Church1,4*, Seth Donoughe1,3,4, Bruno A. S. de Medeiros1 & Cassandra G. Extavour1,2* Over the course of evolution, organism size has diversified markedly. Changes in size are thought to have occurred because of developmental, morphological and/or ecological pressures. To perform phylogenetic tests of the potential effects of these pressures, here we generated a dataset of more than ten thousand descriptions of insect eggs, and combined these with genetic and life-history datasets. We show that, across eight orders of magnitude of variation in egg volume, the relationship between size and shape itself evolves, such that previously predicted global patterns of scaling do not adequately explain the diversity in egg shapes. We show that egg size is not correlated with developmental rate and that, for many insects, egg size is not correlated with adult body size. Instead, we find that the evolution of parasitoidism and aquatic oviposition help to explain the diversification in the size and shape of insect eggs. Our study suggests that where eggs are laid, rather than universal allometric constants, underlies the evolution of insect egg size and shape. Size is a fundamental factor in many biological processes. The size of an 526 families and every currently described extant hexapod order24 organism may affect interactions both with other organisms and with (Fig. 1a and Supplementary Fig. 1). We combined this dataset with the environment1,2, it scales with features of morphology and physi- backbone hexapod phylogenies25,26 that we enriched to include taxa ology3, and larger animals often have higher fitness4. -

No. _Zv_^ _ii ALL RIGHTS RESERVED INTRODUCTION Our grandfathers regarded the study of mythology as a necessary adjunct to a polite education, without a knowledge of which neither the classical nor the more modem poets could be read with understanding. But it is now recognised that upon mythology and folklore rests the basis of the new science of Comparative Religion. The evolution of religion from mythology has now been made plain. It is a law of evolution that, though the parent types which precede certain forms are doomed to perish, they yet bequeath to their descendants certain of their characteristics ; and although mythology has perished (in the civilised world, at least), it has left an indelible stamp not only upon modem religions, but also upon local and national custom. The work of Fruger, Lang, Immerwahr, and others has revolutionised mythology, and has evolved from the unexplained mass of tales of forty years ago a definite and systematic science. -

Euripides-Helen.Pdf
Euripides Helen Helen By Euripides, translation by E. P. Coleridge Revised by the Helen Heroization team (Hélène Emeriaud, Claudia Filos, Janet M. Ozsolak, Sarah Scott, Jack Vaughan) Before the palace of Theoklymenos in Egypt. It is near the mouth of the Nile. The tomb of Proteus, the father of Theoklymenos, is visible. Helen is discovered alone before the tomb. Helen These are the lovely pure streams of the Nile, which waters the plain and lands of Egypt, fed by white melting snow instead of rain from heaven. Proteus was king [turannos] of this land when he was alive, [5] living [oikeîn] on the island of Pharos and lord of Egypt; and he married one of the daughters of the sea, Psamathe, after she left Aiakos' bed. She bore two children in his palace here: a son Theoklymenos, [because he spent his life in reverence of the gods,] [10] and a noble daughter, her mother's pride, called Eido in her infancy. But when she came to youth, the season of marriage, she was called Theonoe; for she knew whatever the gods design, both present and to come, [15] having received these honors [tīmai] from her grandfather Nereus. My own fatherland, Sparta, is not without fame, and my father is Tyndareus; but there is indeed a story that Zeus flew to my mother Leda, taking the form of a bird, a swan, [20] which accomplished the deceitful union, fleeing the pursuit of an eagle, if this story is true. My name is Helen; I will tell the evils [kaka] I have suffered [paskhein]. -
Metamorphoses
Metamorphoses .Like their Greco-Roman counterparts, many Chinese mythical figures become metamorphosed into plants, birds, and anim als, or ob jects such as a dead tree or stone. As Daphne turned into laurel and the sisters o f Phaeton into amber-dropping trees, so Ch’ih Yu’s fetters turned into a grove o f maple trees and Y i Yin’s mother turned into a dead and hollow mulberry tree. As Ganymede (or Deucalion) and Orion turned into the constellations o f Aquarius and Orion, so Fu Yueh became a star, and the two quarreling brothers Yen Po and Shih Ch’en became stars that never crossed paths. As the nymph Psamathe turned into a seal, so Ch’ang O became a toad on the moon. Birds are the most frequent form of metamorphosis, possibly because their winged flight more vividly suggests aerial divinity. Semiramis, who became a dove, Ceyx and Alcyone, who turned into birds, Leda, who metamorphosed into a swan, Nemesis, who became a goose, and Philomela, who turned into the nightingale— all have their counterparts in Chinese gods and goddesses: Ching Wei and Tan Chu became birds, and the emperor o f Shu, Hi Yii, was associated with the nightjar’s call. The correlation between deity and metamorphosed state in the Greco-Roman tradition is often wittily realized. Syrinx turns into a reed as she flees from Pan, who makes a musical instrument from her new form. Narcissus turns into a delicately beautiful water flower, the 189 190 ~ Chinese Mythology narcissus, after he drowns while admiring his reflection in the water. -
Arnold Böcklin's Paradigm Shift
WHEN THE NEREID BECAME MERMAID Arnold BöCklin’s Paradigm Shift [ReCeived 23rd February 2018, aCCepted 15th May 2018, DOI: 10.21463/shima.12.2.09] Han Tran University of Miami <[email protected]> ABSTRACT: Arnold BöCklin’s untraditional depiCtion of the Nereid as mermaid merges two strands that ClassiCal representations of the sea Creature endeavoured to keep separate and that Roman iconography yielded to: the Nereid as idealised, anthropomorphic representative of the Olympian order in the treaCherous realm that is the monster-breeding sea, and the erotiCally Charged objeCt of male attention. His intention, in his own words, was to fuse figure with setting and atmosphere, suCh that the Nereid was no longer simply a figure oCCupying the pictorial spaCe, but embodied in her sensual shape and expression the drawing power of the sea, as well as the vertiginous suggestion of its abysmal depths. BöCklin concludes that the Nereid’s fusion with her environment leads logically to her being conceived as a mermaid, with fishtail. The sea is now no longer, as was the case in ancient iconography, a medium where the Nereid takes gentle rides on the baCk of always Contrasting sea Creatures, without ever seeming to merge with, or be affeCted psyChologiCally by, their disturbing otherness, their difference from her. KEYWORDS: Mermaid, Nereid, Triton, BöCklin, Olympian, RoCk For Freud the unheimliCh is only “outside the house” (the house of the self, the house of culture, the house of the cosmos) insofar as it is hidden within the house. It is a revelation not of the wholly other but of a repressed otherness within the self. -

The scientific accuracy of the creations may not be as im- portant as the learning, reasoning, and imagination used to construct each invention. Invent a Planet: Students may create (draw, paint, montage, build from household or classroom items, what- ever!) a planet. Does it have air? What color is its sky? Does it have ground? What is its ground made of? What is it like on this world? Invent an Alien: Students may create (draw, paint, montage, build from household items, etc.) an alien. To be fair to the alien, they should be sure to provide a way for the alien to get food (what is that food?), a way to breathe (if it needs to), ways to sense the environment, and perhaps a way to move around its planet.
