Curl-up
''Curl-up'' or ''Wentelteefje'' (original Dutch title) is a lithograph print by M. C. Escher, first printed in November 1951. This is the only work by Escher consisting largely of text. The text, which is written in Dutch, describes an imaginary species called ''Pedalternorotandomovens centroculatus articulosus'', also known as “wentelteefje” or “rolpens”. He says this creature came into existence because of the absence in nature of wheel shaped, living creatures with the ability to roll themselves forward. The creature is elongated and armored with several keratinized joints. It has six legs, each with what appears to be a human foot. It has a disc-shaped head with a parrot-like beak and eyes on stalks on either side. It can either crawl over a variety of terrain with its six legs or press its beak to the ground and roll into a wheel shape. It can then roll, gaining acceleration by pushing with its legs. On slopes it can tuck its legs in and roll freely. This rolling c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolling And Wheeled Creatures In Fiction And Legend
Legends and speculative fiction reveal a longstanding human fascination with rolling and wheeled creatures. Such creatures appear in mythologies from Europe, Japan, pre-Columbian Mexico, the United States, and Australia, and in numerous modern works. Rolling creatures The triskelion is a motif with central symmetry used since ancient times. A variant with three human legs appears in the medieval flag of the Isle of Man. A variant with the head of Medusa in the union of the legs is associated with Sicily. It is not known the meaning it had in antiquity or its original Greek name. The hoop snake, a creature of legend in the United States and Australia, is said to grasp its tail in its mouth and roll like a wheel towards its prey. Japanese culture includes a similar mythical creature, the ''Tsuchinoko''. Buer, a demon mentioned in the 16th-century grimoire ''Pseudomonarchia Daemonum'', was described in Collin de Plancy's 1825 edition of ''Dictionnaire Infernal'' as having "the ...

House Of Stairs
''House of Stairs'' is a lithograph print by the Dutch artist M. C. Escher first printed in November 1951. This print measures . It depicts the interior of a tall structure crisscrossed with stairs and doorways. A total of 46 '' wentelteefje'' (imaginary creatures created by Escher) are crawling on the stairs. The ''wentelteefje'' has a long, armored body with six legs, humanoid feet, a parrot-like beak and eyes on stalks. Some are seen to roll in through doors, wound in a wheel shape and then unroll to crawl up the stairs, while others crawl down stairs and wind up to roll out. The ''wentelteefje'' first appeared earlier the same month in the lithograph ''Curl-up ''Curl-up'' or ''Wentelteefje'' (original Dutch title) is a lithograph print by M. C.

Lithography
Lithography () is a planographic method of printing originally based on the immiscibility of oil and water. The printing is from a stone (lithographic limestone) or a metal plate with a smooth surface. It was invented in 1796 by the German author and actor Alois Senefelder and was initially used mostly for musical scores and maps.Meggs, Philip B. A History of Graphic Design. (1998) John Wiley & Sons, Inc. p 146 Carter, Rob, Ben Day, Philip Meggs. Typographic Design: Form and Communication, Third Edition. (2002) John Wiley & Sons, Inc. p 11 Lithography can be used to print text or images onto paper or other suitable material. A lithograph is something printed by lithography, but this term is only used for fine art prints and some other, mostly older, types of printed matter, not for those made by modern commercial lithography. Originally, the image to be printed was drawn with a greasy substance, such as oil, fat, or wax onto the surface of a smooth and flat limestone plat ...

Dutch Language
Dutch ( ) is a West Germanic language spoken by about 25 million people as a first language and 5 million as a second language. It is the third most widely spoken Germanic language, after its close relatives German and English.

Rotating Locomotion In Living Systems
Rotation, or spin, is the circular movement of an object around a '' central axis''. A two-dimensional rotating object has only one possible central axis and can rotate in either a clockwise or counterclockwise direction. A three-dimensional object has an infinite number of possible central axes and rotational directions. If the rotation axis passes internally through the body's own center of mass, then the body is said to be ''autorotating'' or ''spinning'', and the surface intersection of the axis can be called a ''pole''. A rotation around a completely external axis, e.g. the planet Earth around the Sun, is called ''revolving'' or ''orbiting'', typically when it is produced by gravity, and the ends of the rotation axis can be called the ''orbital poles''. Mathematics Mathematically, a rotation is a rigid body movement which, unlike a translation, keeps a point fixed. This definition applies to rotations within both two and three dimensions (in a plane and in space, r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keratin
Keratin () is one of a family of structural fibrous proteins also known as ''scleroproteins''. Alpha-keratin (α-keratin) is a type of keratin found in vertebrates. It is the key structural material making up scales, hair, nails, feathers, horns, claws, hooves, and the outer layer of skin among vertebrates. Keratin also protects epithelial cells from damage or stress. Keratin is extremely insoluble in water and organic solvents. Keratin monomers assemble into bundles to form intermediate filaments, which are tough and form strong unmineralized epidermal appendages found in reptiles, birds, amphibians, and mammals. Excessive keratinization participate in fortification of certain tissues such as in horns of cattle and rhinos, and armadillos' osteoderm. The only other biological matter known to approximate the toughness of keratinized tissue is chitin. Keratin comes in two types, the primitive, softer forms found in all vertebrates and harder, derived forms found only amon ...
