Dog Days (novel)
The dog days or are the hot, sultry days of summer. They were historically the period following the heliacal rising of the star system Sirius (known colloquially as the "Dog Star"), which Hellenistic astrology connected with heat, drought, sudden thunderstorms, lethargy, fever, mad dogs, and bad luck. They are now taken to be the hottest, most uncomfortable part of summer in the Northern Hemisphere. Etymology The English name is a calque of the Latin ' (."the puppy days"), itself a calque of the ancient Greek ''kynádes hēmérai''.. The Greeks knew the star α Canis Majoris by several names, including Sirius "Scorcher" (, ''Seírios''), Sothis (, ''Sôthis'', a transcription of Egyptian '' Spdt''), and the Dog Star (, ''Kúōn'').. The last name reflects the way Sirius follows the constellation Orion into the night sky. History Sirius is by far the brightest proper star in the night sky, which caused ancient astronomers to take note of it around the world. In Egypt, its ...

Summer
Summer is the hottest of the four temperate seasons, occurring after spring and before autumn. At or centred on the summer solstice, the earliest sunrise and latest sunset occurs, daylight hours are longest and dark hours are shortest, with day length decreasing as the season progresses after the solstice. The date of the beginning of summer varies according to climate, tradition, and culture. When it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere, and vice versa. Timing From an astronomical view, the equinoxes and solstices would be the middle of the respective seasons, but sometimes astronomical summer is defined as starting at the solstice, the time of maximal insolation, often identified with the 21st day of June or December. By solar reckoning, summer instead starts on May Day and the summer solstice is Midsummer. A variable seasonal lag means that the meteorological centre of the season, which is based on average temperature pattern ...

Iliad
The ''Iliad'' (; grc, Ἰλιάς, Iliás, ; "a poem about Ilium") is one of two major ancient Greek epic poems attributed to Homer. It is one of the oldest extant works of literature still widely read by modern audiences. As with the ''Odyssey'', the poem is divided into 24 books and contains 15,693 lines in its most widely accepted version, and was written in dactylic hexameter. Set towards the end of the Trojan War, a ten-year siege of the city of Troy by a coalition of Mycenaean Greek states, the poem depicts significant events in the siege's final weeks. In particular, it depicts a fierce quarrel between King Agamemnon and a celebrated warrior, Achilles. It is a central part of the Epic Cycle. The ''Iliad'' is often regarded as the first substantial piece of European literature. The ''Iliad'', and the ''Odyssey'', were likely written down in Homeric Greek, a literary amalgam of Ionic Greek and other dialects, probably around the late 8th or early 7th century BC. Homer's ...

Homer
Homer (; grc, Ὅμηρος , ''Hómēros'') (born ) was a Greek poet who is credited as the author of the ''Iliad'' and the ''Odyssey'', two epic poems that are foundational works of ancient Greek literature. Homer is considered one of the most revered and influential authors in history. Homer's ''Iliad'' centers on a quarrel between King Agamemnon and the warrior Achilles during the last year of the Trojan War. The ''Odyssey'' chronicles the ten-year journey of Odysseus, king of Ithaca, back to his home after the fall of Troy. The poems are in Homeric Greek, also known as Epic Greek, a literary language which shows a mixture of features of the Ionic and Aeolic dialects from different centuries; the predominant influence is Eastern Ionic. Most researchers believe that the poems were originally transmitted orally. Homer's epic poems shaped aspects of ancient Greek culture and education, fostering ideals of heroism, glory, and honor. To Plato, Homer was simply the one who ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Greek Poetry
Greek literature () dates back from the ancient Greek literature, beginning in 800 BC, to the modern Greek literature of today. Ancient Greek literature was written in an Ancient Greek dialect, literature ranges from the oldest surviving written works until works from approximately the fifth century AD. This time period is divided into the Preclassical, Classical, Hellenistic, and Roman periods. Preclassical Greek literature primarily revolved around myths and include the works of Homer; the ''Iliad'' and the ''Odyssey''. The Classical period saw the dawn of drama and history. Three philosophers are especially notable: Socrates, Plato, and Aristotle. During the Roman era, significant contributions were made in a variety of subjects, including history, philosophy, and the sciences. Byzantine literature, the literature of the Byzantine Empire, was written in Atticizing, Medieval and early Modern Greek. Chronicles, distinct from historics, arose in this period.

Ancient Greece
Ancient Greece ( el, Ἑλλάς, Hellás) was a northeastern Mediterranean civilization, existing from the Greek Dark Ages of the 12th–9th centuries BC to the end of classical antiquity ( AD 600), that comprised a loose collection of culturally and linguistically related city-states and other territories. Most of these regions were officially unified only once, for 13 years, under Alexander the Great's empire from 336 to 323 BC (though this excludes a number of Greek city-states free from Alexander's jurisdiction in the western Mediterranean, around the Black Sea, Cyprus, and Cyrenaica). In Western history, the era of classical antiquity was immediately followed by the Early Middle Ages and the Byzantine period. Roughly three centuries after the Late Bronze Age collapse of Mycenaean Greece, Greek urban poleis began to form in the 8th century BC, ushering in the Archaic period and the colonization of the Mediterranean Basin. This was followed by the age of Classical G ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Flooding Of The Nile
The flooding of the Nile has been an important natural cycle in Egypt since Ancient Egypt, ancient times. It is celebrated by Egyptians as an annual holiday for two weeks starting August 15, known as ''Wafaa El-Nil''. It is also celebrated in the Coptic Orthodox Church of Alexandria, Coptic Church by ceremonially throwing a martyr's relic into the river, hence the name, The Martyr's Finger (, ). The flooding of the Nile was poetically described in myth as Isis's tears of sorrow for Osiris myth, Osiris when killed by their brother Set (deity), Set. Flooding cycle The flooding of the Nile is the result of the yearly monsoon between May and August causing enormous precipitations on the Ethiopian Highlands whose summits reach heights of up to 4550 m (14,928 ft). Most of this rainwater is taken by the Blue Nile and by the Atbarah River into the Nile, while a less important amount flows through the Sobat River, Sobat and the White Nile into the Nile. During this short period, those ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ancient Astronomers
Astronomy is the oldest of the natural sciences, dating back to Ancient history, antiquity, with its origins in the Religion, religious, mythological, Archaeoastronomy#Myth and cosmology, cosmological, Archaeoastronomy#The use of calendars, calendrical, and Astrology, astrological beliefs and practices of prehistory: vestiges of these are still found in astrology, a discipline long interwoven with public and governmental astronomy. It was not completely separated in Europe (see astrology and astronomy) during the Copernican Revolution starting in 1543. In some cultures, astronomical data was used for astrological prognostication. Early history Early cultures identified celestial objects with mythology, gods and spirits. They related these objects (and their movements) to phenomena such as rain, drought, seasons, and tides. It is generally believed that the first astronomers were priests, and that they understood Astronomical object, celestial objects and events to be manifestat ...

Night Sky
The night sky is the nighttime appearance of celestial objects like stars, planets, and the Moon, which are visible in a clear sky between sunset and sunrise, when the Sun is below the horizon. Natural light sources in a night sky include moonlight, starlight, and airglow, depending on location and timing. Aurorae light up the skies above the polar circles. Occasionally, a large coronal mass ejection from the Sun or simply high levels of solar wind may extend the phenomenon toward the Equator. The night sky and studies of it have a historical place in both ancient and modern cultures. In the past, for instance, farmers have used the status of the night sky as a calendar to determine when to plant crops. Many cultures have drawn constellations between stars in the sky, using them in association with legends and mythology about their deities. The anciently developed belief of astrology is generally based on the belief that relationships between heavenly bodies infl ...

Apparent Magnitude
Apparent magnitude () is a measure of the brightness of a star or other astronomical object observed from Earth. An object's apparent magnitude depends on its intrinsic luminosity, its distance from Earth, and any extinction of the object's light caused by interstellar dust along the line of sight to the observer. The word ''magnitude'' in astronomy, unless stated otherwise, usually refers to a celestial object's apparent magnitude. The magnitude scale dates back to the ancient Roman astronomer Claudius Ptolemy, whose star catalog listed stars from 1st magnitude (brightest) to 6th magnitude (dimmest). The modern scale was mathematically defined in a way to closely match this historical system. The scale is reverse logarithmic: the brighter an object is, the lower its magnitude number. A difference of 1.0 in magnitude corresponds to a brightness ratio of \sqrt /math>, or about 2.512. For example, a star of magnitude 2.0 is 2.512 times as bright as a star of magnitude 3.0, 6. ...
