Avalon

Avalon (/ˈævəˌlɒn/; Welsh: Ynys Afallon; probably from afal, meaning "apple") is a legendary island featured in the Arthurian legend. It first appears in Geoffrey of Monmouth's 1136 pseudohistorical account Historia Regum Britanniae ("The History of the Kings of Britain") as the place where King Arthur's sword Excalibur was forged and later where Arthur was taken to recover from his wounds after the Battle of Camlann. Avalon was associated from an early date with mystical practices and people such as Morgan le Fay.

Etymology

Geoffrey of Monmouth referred to it in Latin as Insula Avallonis in the Historia. In the later Vita Merlini he called it Insula Pomorum the "isle of fruit trees" (from Latin pōmus "fruit tree"). The name is generally considered to be of Welsh origin (though an Old Cornish or Old Breton origin is also possible), derived from Old Welsh aball, "apple/fruit tree" (in later Middle Welsh spelled avall; now Modern Welsh afall). In Breton, apple is spelled "aval"/ "avaloù" in plural. It is also possible that the tradition of an "apple" island among the British was influenced by Irish legends concerning the otherworld island home of Manannán mac Lir and Lugh, Emain Ablach (also the Old Irish poetic name for the Isle of Man), where Ablach means "Having Apple Trees" – derived from Old Irish aball ("apple")—and is similar to the Middle Welsh name Afallach, which was used to replace the name Avalon in medieval Welsh translations of French and Latin Arthurian tales. All are etymologically related to the Gaulish root *aballo- (as found in the place name Aballo/Aballone, now Avallon in Burgundy or in the Italian surname Avallone) and are derived from a Common Celtic *abal- "apple", which is related at the Proto-Indo-European level to English apple, Russian яблоко (jabloko), Latvian ābele, et al.

Tower

A tower is a tall structure, taller than it is wide, often by a significant margin. Towers are distinguished from masts by their lack of guy-wires and are therefore, along with tall buildings, self-supporting structures.

Towers are specifically distinguished from "buildings" in that they are not built to be habitable but to serve other functions. The principal function is the use of their height to enable various functions to be achieved including: visibility of other features attached to the tower such clock towers; as part of a larger structure or device to increase the visibility of the surroundings as in a fortified building such as a castle; or as a structural feature as an integral part of a bridge.

Towers can be stand alone structures or be supported by adjacent buildings or can be a feature on top of a large structure or building.

History

Towers have been used by mankind since prehistoric times. The oldest known may be the circular stone tower in walls of Neolithic Jericho (8000 BC). Some of the earliest towers were ziggurats, which existed in Sumerian architecture since the 4th millennium BC. The most famous ziggurats include the Sumerian Ziggurat of Ur, built the 3rd millennium BC, and the Etemenanki, one of the most famous examples of Babylonian architecture. The latter was built in Babylon during the 2nd millennium BC and was considered the tallest tower of the ancient world.
