Denis's Ear
The Ear of Dionysius ( it, Orecchio di Dionisio) is a limestone cave carved out of the Temenites hill in the city of Syracuse, on the island of Sicily in Italy. Its name, given by the painter Michelangelo da Caravaggio, comes from its similarity in shape to the human ear. The name is also linked to the acoustic effects inside the cave: it is said that people's voices echo up to 16 times. Geology The Ear of Dionysius was most likely formed out of an old limestone quarry. It is 23 metres high and extends 65 metres back into the cliff. Horizontally, it bends in an approximate "S" shape, vertically it is tapered at the top like a teardrop. Because of its shape the Ear has extremely good acoustics, making even a small sound resonate throughout the cave. Purpose This cave was dug in Greek/Roman times as a water storage for Syracuse. A narrow tunnel was dug first. This tunnel was widened by digging down and sideways afterwards, giving the cave its unusual shape. The small narrow tu ...

Painting
Painting is the practice of applying paint, pigment, color or other medium to a solid surface (called the "matrix" or "support"). The medium is commonly applied to the base with a brush, but other implements, such as knives, sponges, and airbrushes, can be used. In art, the term ''painting ''describes both the act and the result of the action (the final work is called "a painting"). The support for paintings includes such surfaces as walls, paper, canvas, wood, glass, lacquer, pottery, leaf, copper and concrete, and the painting may incorporate multiple other materials, including sand, clay, paper, plaster, gold leaf, and even whole objects. Painting is an important form in the visual arts, bringing in elements such as drawing, composition, gesture (as in gestural painting), narration (as in narrative art), and abstraction (as in abstract art). Paintings can be naturalistic and representational (as in still life and landscape painting), photographic, abstract, nar ...

Archaeological Sites In Sicily
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes over 99% of the human past, from the Paleolithic until the advent of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ear Trumpet
An ear trumpet is a tubular or funnel-shaped device which collects sound waves and leads them into the ear. They were used as hearing aids, resulting in a strengthening of the sound energy impact to the eardrum and thus improved hearing for a deaf or hard-of-hearing individual. Ear trumpets were made of sheet metal, silver, wood, snail shells or animal horns. They have largely been replaced in wealthier areas of the world by modern hearing aid technology that is much smaller and less obtrusive, albeit more expensive. A sound trumpet does not "amplify" sound. It takes the sound power received over a large area and concentrates it into a smaller area. The received sound is louder, but no power has been created in the process. History The use of ear trumpets for the partially deaf dates back to the 17th century.Howard, Alexander. "Hearing Aids: Smaller and Smarter." New York Times, November 26, 1998. The earliest description of an ear trumpet was given by the French Jesuit priest a ...

Prison
A prison, also known as a jail, gaol (dated, standard English, Australian, and historically in Canada), penitentiary (American English and Canadian English), detention center (or detention centre outside the US), correction center, correctional facility, lock-up, hoosegow or remand center, is a facility in which inmates (or prisoners) are confined against their will and usually denied a variety of freedoms under the authority of the state as punishment for various crimes. Prisons are most commonly used within a criminal justice system: people charged with crimes may be imprisoned until their trial; those pleading or being found guilty of crimes at trial may be sentenced to a specified period of imprisonment. In simplest terms, a prison can also be described as a building in which people are legally held as a punishment for a crime they have committed. Prisons can also be used as a tool of political repression by authoritarian regimes. Their perceived opponents may be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Legend
A legend is a Folklore genre, genre of folklore that consists of a narrative featuring human actions, believed or perceived, both by teller and listeners, to have taken place in human history. Narratives in this genre may demonstrate human values, and possess certain qualities that give the tale verisimilitude (literature), verisimilitude. Legend, for its active and passive participants may include miracles. Legends may be transformed over time to keep them fresh and vital. Many legends operate within the realm of uncertainty, never being entirely believed by the participants, but also never being resolutely doubted. Legends are sometimes distinguished from myths in that they concern human beings as the main characters rather than gods, and sometimes in that they have some sort of historical basis whereas myths generally do not. The Brothers Grimm defined ''legend'' as "Folklore, folktale historically grounded". A by-product of the "concern with human beings" is the long list o ...

Dionysius I Of Syracuse
Dionysius I or Dionysius the Elder ( 432 – 367 BC) was a Greek tyrant of Syracuse, in Sicily. He conquered several cities in Sicily and southern Italy, opposed Carthage's influence in Sicily and made Syracuse the most powerful of the Western Greek colonies. He was regarded by the ancients as an example of the worst kind of despot—cruel, suspicious and vindictive. Endnotes: * Diod. Sic. xiii., xiv., xv. *J. Bass, ''Dionysius I. von Syrakus'' (Vienna, 1881), with full references to authorities in footnotes Early life of Dionysius the Elder Dionysius began his working life as a clerk in a public office. Because of his achievements in the war against Carthage that began in 409 BC, he was elected supreme military commander in 406 BC. In the following year he seized total power and became tyrant. He was married to Aristomache, and had a daughter by her, Arete. He was married at the same time to Doris of Locris, who bore him his son, Dionysius II of Syracuse. Rise to power Dionysiu ...

Vincenzo Mirabella
Vincenzo Mirabella Alagona (Syracuse, Sicily 1570 - Modica, 1624) was an Italian historian, archaeologist and architect, best known for his work ''Plans of Ancient Syracuse''. Family life Vincenzo Mirabella, son of Michele Mirabella and Giovanna Alagona, was born into a patrician family of French origin which had moved to Sicily in the early fourteenth century. As a young man he dedicated himself to the study of Greek, Latin and Italian literature as well as mathematics, music, history and poetry. He played an active part in civic life, holding office as ''magister nundinarum'' (Master of the Assizes) in 1593, Treasurer of the University in 1613-14 and Jurat, the highest office in the city, in 1616-17. He married Lucrezia Platamone, daughter of Antonio and Giovanna Zumbo, who brought him a substantial dowry and further connections to the leading families of Syracuse. He does not appear to have had any children with her. He lived in a house in Syracuse in front of the Church of S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Resonance
Resonance describes the phenomenon of increased amplitude that occurs when the frequency of an applied periodic force (or a Fourier component of it) is equal or close to a natural frequency of the system on which it acts. When an oscillating force is applied at a resonant frequency of a dynamic system, the system will oscillate at a higher amplitude than when the same force is applied at other, non-resonant frequencies. Frequencies at which the response amplitude is a relative maximum are also known as resonant frequencies or resonance frequencies of the system. Small periodic forces that are near a resonant frequency of the system have the ability to produce large amplitude oscillations in the system due to the storage of vibrational energy. Resonance phenomena occur with all types of vibrations or waves: there is mechanical resonance, orbital resonance, acoustic resonance, electromagnetic resonance, nuclear magnetic resonance (NMR), electron spin resonance (ESR) and reso ...
