Toadstone
The toadstone, also known as bufonite (from Latin , "toad"), is a mythical stone or gem that was thought to be found in the head of a toad. It was supposed to be an antidote to poison and in this it is like batrachite, supposedly formed in the heads of frogs. Toadstones were actually the button-like fossilised teeth of ''Lepidotes'', an extinct genus of ray-finned fish from the Jurassic and Cretaceous periods. They appeared to be "stones that are perfect in form" and were set by European jewellers into magical rings and amulets from Medieval times until the 18th century. Beliefs From ancient times people associated the fossils with jewels that were set inside the heads of toads. The toad has poison glands in its skin, so it was naturally assumed that they carried their own antidote and that this took the form of a magical stone. They were first recorded by Pliny the Elder in the first century. According to Paul Taylor of the London Natural History Museum: The true toadst ...

Toad
Toad is a common name for certain frogs, especially of the family Bufonidae, that are characterized by dry, leathery skin, short legs, and large bumps covering the parotoid glands. A distinction between frogs and toads is not made in scientific taxonomy, but is common in popular culture (folk taxonomy), in which toads are associated with drier, rougher skin and more terrestrial habitats. List of toad families In scientific taxonomy, toads include the true toads (Bufonidae) and various other terrestrial or warty-skinned frogs. Non-bufonid "toads" can be found in the families: * Bombinatoridae ( fire-bellied toads and jungle toads) * Calyptocephalellidae (helmeted water toad and false toads) * Discoglossidae ( midwife toads) * Myobatrachidae (Australian toadlets) * Pelobatidae (European spadefoot toad) * Rhinophrynidae ( burrowing toads) * Scaphiopodidae (American spadefoot toads) * Microhylidae ( narrowmouth toads) Biology Usually the largest of the bumps on the skin ...

Bezoar
A bezoar is a mass often found trapped in the gastrointestinal system, though it can occur in other locations. A pseudobezoar is an indigestible object introduced intentionally into the digestive system. There are several varieties of bezoar, some of which have inorganic constituents and others organic. The term has both a modern (medical, scientific) and traditional usage. Types By content * Food boluses (or boli; singular bolus) have the archaic and positive meaning of bezoar, and are composed of loose aggregates of food items such as seeds, fruit pith, or pits, as well as other types of items such as shellac, bubble gum, soil, and concretions of some medications. * Lactobezoars are a specific type of food bezoar comprising inspissated milk. It is most commonly seen in premature infants receiving formula foods. * Pharmacobezoars (or medication bezoars) are mostly tablets or semiliquid masses of drugs, normally found following overdose of sustained-release medications. * Phy ...

Lepidotes Elvensis Skull
''Lepidotes'' (from el, λεπιδωτός , 'covered with scales') (previously known as ''Lepidotus'') is an extinct genus of Mesozoic ray-finned fish. It has been considered a wastebasket taxon, characterised by "general features, such as thick rhomboid scales and, for most of the species, by semi-tritorial or strongly with dozens of species assigned to it. Fossils attributed to ''Lepidotes'' have been found in Jurassic and Cretaceous rocks worldwide.López-Arbarello, A. (2012).Phylogenetic Interrelationships of Ginglymodian Fishes (Actinopterygii: Neopterygii). ''PLoS One'', 7(7): e39370. It has been argued that ''Lepidotes'' should be restricted to species closely related to the type species ''L. gigas,'' which are only known from the Early Jurassic of Central Europe, with most other species being not closely related, with other species transferred to new genera such as ''Scheenstia.'' ''Lepidotes'' belongs to Ginglymodi, a clade of fish whose only living representatives are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biomineralization
Biomineralization, also written biomineralisation, is the process by which living organisms produce minerals, often to harden or stiffen existing tissues. Such tissues are called mineralized tissues. It is an extremely widespread phenomenon; all six taxonomic kingdoms contain members that are able to form minerals, and over 60 different minerals have been identified in organisms. Examples include silicates in algae and diatoms, carbonates in invertebrates, and calcium phosphates and carbonates in vertebrates. These minerals often form structural features such as sea shells and the bone in mammals and birds. Organisms have been producing mineralized skeletons for the past 550 million years. Calcium carbonates and calcium phosphates are usually crystalline, but silica organisms (sponges, diatoms...) are always non crystalline minerals. Other examples include copper, iron and gold deposits involving bacteria. Biologically formed minerals often have special uses such as magnetic ...

Alessandro De Medici
Alessandro de' Medici (22 July 1510 – 6 January 1537), nicknamed "il Moro" due to his dark complexion, Duke of Penne and the first Duke of the Florentine Republic (from 1532), was ruler of Florence from 1530 to his death in 1537. The first Medici to rule Florence as a hereditary monarch, Alessandro was also the last Medici from the senior line of the family to lead the city. His assassination at the hands of distant cousin Lorenzaccio caused the title of Duke to pass to Cosimo I de Medici, from the family's junior branch. Life Born in Florence, Alessandro was recognized by a plurality of his contemporaries as the only son of Lorenzo II de' Medici, grandson of Lorenzo de' Medici "the Magnificent". Others believed him to be the illegitimate son of Giulio de' Medici (later Pope Clement VII), but at the time that was a minority view.Catherine Fletcher, ''The Black Prince of Florence: The Spectacular Life and Treacherous World of Alessandro de' Medici'' (London: Bodley Head, 2016), ...

James Branch Cabell
James Branch Cabell (; April 14, 1879 – May 5, 1958) was an American author of fantasy fiction and ''belles-lettres''. Cabell was well-regarded by his contemporaries, including H. L. Mencken, Edmund Wilson, and Sinclair Lewis. His works were considered escapist and fit well in the culture of the 1920s, when they were most popular. For Cabell, veracity was "the one unpardonable sin, not merely against art, but against human welfare." Although escapist, Cabell's works are ironic and satirical. Mencken disputed Cabell's claim to romanticism and characterized him as "really the most acidulous of all the anti-romantics. His gaudy heroes ... chase dragons precisely as stockbrockers play golf." Cabell saw art as an escape from life, but found that, once the artist creates his ideal world, it is made up of the same elements that make the real one. Interest in Cabell declined in the 1930s, a decline that has been attributed in part to his failure to move out of his fantasy ...

As You Like It
''As You Like It'' is a pastoral comedy by William Shakespeare believed to have been written in 1599 and first published in the First Folio in 1623. The play's first performance is uncertain, though a performance at Wilton House in 1603 has been suggested as a possibility. ''As You Like It'' follows its heroine Rosalind as she flees persecution in her uncle's court, accompanied by her cousin Celia to find safety and, eventually, love, in the Forest of Arden. In the forest, they encounter a variety of memorable characters, notably the melancholy traveller Jaques, who speaks many of Shakespeare's most famous speeches (such as "All the world's a stage", "too much of a good thing" and "A fool! A fool! I met a fool in the forest"). Jaques provides a sharp contrast to the other characters in the play, always observing and disputing the hardships of life in the country. Historically, critical response has varied, with some critics finding the play a work of great merit and some f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shakespeare's
William Shakespeare ( 26 April 1564 – 23 April 1616) was an English playwright, poet and actor. He is widely regarded as the greatest writer in the English language and the world's pre-eminent dramatist. He is often called England's national poet and the "Bard of Avon" (or simply "the Bard"). His extant works, including collaborations, consist of some 39 plays, 154 sonnets, three long narrative poems, and a few other verses, some of uncertain authorship. His plays have been translated into every major living language and are performed more often than those of any other playwright. He remains arguably the most influential writer in the English language, and his works continue to be studied and reinterpreted. Shakespeare was born and raised in Stratford-upon-Avon, Warwickshire. At the age of 18, he married Anne Hathaway, with whom he had three children: Susanna, and twins Hamnet and Judith. Sometime between 1585 and 1592, he began a successful career in London as an ac ...

Allusion
Allusion is a figure of speech, in which an object or circumstance from unrelated context is referred to covertly or indirectly. It is left to the audience to make the direct connection. Where the connection is directly and explicitly stated (as opposed to indirectly implied) by the author, it is instead usually termed a reference. In the arts, a literary allusion puts the alluded text in a new context under which it assumes new meanings and denotations. It is not possible to predetermine the nature of all the new meanings and inter-textual patterns that an allusion will generate. Literary allusion is closely related to parody and pastiche, which are also "text-linking" literary devices.Ben-Porot (1976) pp. 107–8 quotation: In a wider, more informal context, an allusion is a passing or casually short statement indicating broader meaning. It is an incidental mention of something, either directly or by implication, such as "In the stock market, he met his Waterloo." Scope of th ...

British Museum
The British Museum is a public museum dedicated to human history, art and culture located in the Bloomsbury area of London. Its permanent collection of eight million works is among the largest and most comprehensive in existence. It documents the story of human culture from its beginnings to the present.Among the national museums in London, sculpture and decorative and applied art are in the Victoria and Albert Museum; the British Museum houses earlier art, non-Western art, prints and drawings. The National Gallery holds the national collection of Western European art to about 1900, while art of the 20th century on is at Tate Modern. Tate Britain holds British Art from 1500 onwards. Books, manuscripts and many works on paper are in the British Library. There are significant overlaps between the coverage of the various collections. The British Museum was the first public national museum to cover all fields of knowledge. The museum was established in 1753, largely b ...

Ashmolean Museum
The Ashmolean Museum of Art and Archaeology () on Beaumont Street, Oxford, England, is Britain's first public museum. Its first building was erected in 1678–1683 to house the cabinet of curiosities that Elias Ashmole gave to the University of Oxford in 1677. It is also the world's second university museum, after the establishment of the Kunstmuseum Basel in 1661 by the University of Basel. The present building was built between 1841 and 1845. The museum reopened in 2009 after a major redevelopment, and in November 2011, new galleries focusing on Egypt and Nubia were unveiled. In May 2016, the museum also opened redisplayed galleries of 19th-century art. History Broad Street The museum opened on 24 May 1683, with naturalist Robert Plot as the first keeper. The building on Broad Street (later known as the Old Ashmolean) is sometimes attributed to Sir Christopher Wren or Thomas Wood. Elias Ashmole had acquired the collection from the gardeners, travellers, and collectors Joh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
