Methone (butterfly)
''Methone'' is a genus in the butterfly family Riodinidae present only in the Neotropical realm. Taxonomy The genus ''Methone'' is monotypic. The single species is ''Methone cecilia'' is unmistakably characterized by the conspicuous colouring and the deeply indented margin of the hindwing being continued in the female at the ends of the veins into teeth-like small tails. On the forewing the subcostal is four-branched; the branches 1 and 2 rise before, 3 and 4 behind the cell. The hindwing is without a basal vein. The palpi are extremely short. The colouring resembles that of certain '' Themone'', '' Cartea,'' '' Monethe'', '' Aricoris'' which imitate butterflies such as Ithomiinae and pericopine moths. The females are very stout and clumsy which makes them still more similar to the unwieldy ''Actinote''. They are quite common but they are local and seem not to leave their birthplace.

Methone (moon)
Methone is a small, egg-shaped moon of Saturn that orbits out past Saturn's ring system, between the orbits of Mimas and Enceladus. It was discovered in 2004, though it wasn't until 2012 that it was imaged in detail by the '' Cassini'' spacecraft. History Methone was first discovered by the Cassini Imaging Team and given the temporary designation . Methone is also named (32). The '' Cassini'' spacecraft made two visits to Methone, and its closest approach was made on May 20, 2012 with a minimum distance of from it. The name Methone was approved by the IAU Working Group on Planetary System Nomenclature on January 21, 2005. It was ratified at the IAU General Assembly in 2006. Methone (Greek ''Μεθώνη'') was one of the Alkyonides, the seven beautiful daughters of the Giant Alkyoneus. Orbit Methone's orbit is perturbed by a 14:15 mean-motion resonance with the much larger Mimas. This causes its osculating orbital elements to vary with an amplitude of about in semi-ma ...

Methone (Greek Myth)
In Greek mythology, Methone (Ancient Greek: Μεθώνη) was the name shared by the three women: * Methone, one of the Alcyonides, daughters of the giant Alcyoneus. She was the sister of Alkippe, Anthe, Asteria, Drimo, Pallene and Phthonia ( Phosthonia or Chthonia). When their father Alcyoneus was slain by Heracles, these girls threw themselves into the sea from Kanastraion, which is the peak of Pellene. They were then transformed into halcyons (kingfishers) by the goddess Amphitrite. * Methone, the nymph-consort of Pierus, king of Pieria, and by the latter, became the mother of Oeagrus, father of Orpheus. In some accounts rather, she was called the sister of Pierus. * Methone or Mothone (Μοθώνη), a bastard daughter of King Oeneus of Calydon by a concubine. She was the eponymous heroine who gave her name to Methone in Messenia. *Methone, wife of King Poeas of Meliboea and mother of Philoctetes. Otherwise, the latter's mother was called Demonassa.Hyginus, ''Fabulae'10 ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Dimedone
Dimedone is a cyclic diketone used in organic chemistry to determine whether a compound contains an aldehyde group. Cyclohexanediones in general can be used as catalysts in the formation of transition-metal complexes. Other uses include applications in colorimetry, crystallography, luminescence and spectrophotometric analysis. It can also be used for chemistry involving organic compounds of low electrical resistance. Synthesis Dimedone is prepared from mesityl oxide and diethyl malonate. Physical properties Dimedone usually comes in the form of white crystals. It is stable under ambient conditions and soluble in water, as well as ethanol and methanol. It has a melting point range of 147–150 °C (420–423 K). Chemical properties Tautomerism Dimedone is in equilibrium with its tautomer Tautomers () are structural isomers (constitutional isomers) of chemical compounds that readily interconvert. The chemical reaction interconverting the two is called tautomeriz ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Methone (Messenia)
Methone ( grc, Μεθώνη), or Mothone (Μοθώνη), was a town in the southwestern corner of ancient Messenia. It was an important place in ancient times, on account of its excellent harbour and salubrious situation. It is situated at the extreme point of a rocky ridge, which runs into the sea, opposite the island Sapientza, one of the group called in ancient times Oenussae. Off the outer end of the town, is the little insulated rock which Pausanias (geographer), Pausanias calls Mothon, and which he describes as forming at once a narrow entrance and a shelter to the harbour of his time: in the 19th century, when visited by William Martin Leake, it was occupied by a tower and lantern, which is connected by a bridge with the fortification of Methoni, Messenia, modern Methoni. A mole branched from it, which ran parallel to the eastern wall of the town, and forms a harbour for small vessels, which to Leake seems to be exactly in the position of the ancient port, the entrance into whi ...

Methone (Thessaly)
Methone ( grc, Μεθώνη) was a town and polis (city-state) on the Pagasetic Gulf of ancient Magnesia, Magnesia in ancient Thessaly. The town is mentioned by Homer in the Catalogue of Ships in the ''Iliad'' as belonging to Philoctetes. It is also mentioned in the Periplus of Pseudo-Scylax as a city in Magnesia, together with Iolcus, Coracae, Spalauthra and Olizon. Some accept that the town's location is on a hill called Nevestiki (), near the current village of Ano Lechonia, where remains of a fortification have been found, but that location has been suggested by others as the site of Coracae.

Methoni, Pieria
Methoni ( el, Μεθώνη Πιερίας) is a village and a former municipality in Pieria regional unit, Greece. Since the 2011 local government reform it is part of the municipality Pydna-Kolindros, of which it is a municipal unit. History The ancient Eretrian settlement of Methone, located at the interface between the Thessaloniki plain, the hilly terrain of Pieria and the shoreline of Thermaic Gulf, has gone through numerous wartime situations over the past centuries. Methone has been well known as an important harbor during the Greek times closely affiliated with the Athenian Alliance. According to historical manuscripts the urban settlement was distanced from the harbor. However, there exist no historical references about either the distance or the potential locations of the harbor. Identification of the precise location of the port of Methone holds great significance from a geomorphological point of view, but above all represents a major archaeological concern. The por ...

Ancient Methone
Ancient Methone ( gr, Μεθώνη), also called Thracian or Macedonian Methone to distinguish it from Messenian Methone was a polis in Ancient Greece, near the city of Pydna and the modern village of Nea Agathoupolis in Pieria. According to Plutarch, Methone was founded as a Greek colony in the year 733/732 BC. Methone gained special importance by the finding of labeled pottery and potsherds. It is one of the oldest testimonies of Greek writing and an important place in the history of Pieria. Location The ancient city of Methone was located on the northeastern shore of the Thermaic Gulf, in the northern Aegean in Greece. It was right on the sea, north of the modern town of Methoni. Due to the deposition of sediments, especially of the river Aliakmonas, the ancient village is now about 500 m distant from the coast. The archaeological remains of the city consist of buildings on the west and east hills and had a harbor. Around 700 BC the city had an area of about 20 he ...

Meton Of Athens
Meton of Athens ( el, Μέτων ὁ Ἀθηναῖος; ''gen''.: Μέτωνος) was a Greek mathematician, astronomer, geometer, and engineer who lived in Athens in the 5th century BC. He is best known for calculations involving the eponymous 19-year Metonic cycle, which he introduced in 432 BC into the lunisolar Attic calendar. Euphronios says that Colonus was Meton's deme. Work The Metonic calendar incorporates knowledge that 19 solar years and 235 lunar months are very nearly of the same duration. Consequently, a given day of a lunar month will often occur on the same day of the solar year as it did 19 years previously. Meton's observations were made in collaboration with Euctemon, about whom nothing else is known. The Greek astronomer Callippus expanded on the work of Meton, proposing what is now called the Callippic cycle. A Callippic cycle runs for 76 years, or four Metonic cycles. Callippus refined the lunisolar calendar, deducting one day from the fourth Metonic cy ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
