An idiosyncrasy is a unique feature of something. The term is often used to express peculiarity.
55-608: A geis or geas (pl. geasa ) is an idiosyncratic taboo , whether of obligation or prohibition, similar to being under a vow or curse , yet the observance of which can also bring power and blessings. It is also used to mean specifically a spell prohibiting some action. Geasa are common in Irish and Scottish folklore and mythology, as well as in modern English-language fantasy fiction. The word originates in Old Irish, also known as Old Gaelic , and retains
110-513: A curse or paradoxically a gift. If someone under a geas violates the associated taboo, the infractor will suffer dishonor or even death. Conversely, the observing of one's geas is believed to bring power. Often, women place geasa upon men; in some cases, the woman turns out to be a goddess or other sovereignty figure. The geas is often a key device in hero tales, such as that of Cú Chulainn in Irish mythology . Traditionally,
165-465: A systematic regularity . While systematic regularities in the sound system of a language are useful for identifying phonological rules during analysis of the forms morphemes can take, idiosyncratic properties are those whose occurrence is not determined by those rules. For example, the fact that the English word cab starts with the sound /k/ is an idiosyncratic property; on the other hand that its vowel
220-630: A bride and groom escape a barbaric marriage custom in Ireland. According to the British scholar W.D. Howarth, Cervantes was inspired by Peruvian marriage ceremonies and what is described is different from the classic version of the droit du seigneur as it involves multiple virgins. However, Cervantes' story was a source for the English play The Custom of the Country , written by John Fletcher and Philip Massinger and published in 1647. The play has
275-430: A complete market in which the capital asset pricing model holds, the price of a security is determined by the amount of systematic risk in its returns. Net income received, or losses suffered, by a landlord from renting of one or two properties is subject to idiosyncratic risk due to the numerous things that can happen to real property and variable behavior of tenants. According to one macroeconomic model including
330-443: A financial sector, hedging idiosyncratic risk can be self-defeating as amid the "risk reduction" experts are encouraged to increase their leverage. This works for small shocks but leads to higher vulnerability for larger shocks and makes the system less stable. Thus, while securitisation in principle reduces the costs of idiosyncratic shocks, it ends up amplifying systemic risks in equilibrium. In econometrics , "idiosyncratic error"
385-459: A following of one's particular temperament or bent especially in trait, trick, or habit; the former often suggests mental aberration, the latter, strong individuality and independence of action". The term can also be applied to symbols or words. Idiosyncratic symbols mean one thing for a particular person, as a blade could mean war , but to someone else, it could symbolize a surgery . In phonology , an idiosyncratic property contrasts with
440-436: A payment for the droit du seigneur to be waived. Alternatively, it has been interpreted as compensation to the lord for the young women leaving his lands. Encyclopædia Britannica states that the evidence indicates it was a monetary tax related to vassal marriages, since a considerable number of seigneurial rights revolved around marriage. A similar payment to church authorities has also been interpreted as relating to
495-617: A polemic against medieval barbarism. Other Scottish scholars of his era quoted Boece with approval, including John Lesley (1578), George Buchanan (1582), and Habbakuk Bisset (1626). The historical existence of the custom in Scotland was also accepted in Scottish legal works such as James Balfour 's Practicks ( c. 1579 ), John Skene 's De Verborum (1597), and Thomas Craig 's Jus Feudale (1603). The English scholar Henry Spelman stated in his Glossary (1664) that

Geas , geis and derivative words and concepts have appeared in a variety of forms in popular culture. In Pirates of the Caribbean: At World's End , Governor Weatherby Swann was going to stab the heart of Davy Jones , only for Jones to reveal that he cast
605-518: A similar custom among the Adyrmachidae in ancient Libya : "They are also the only tribe with whom the custom obtains of bringing all women about to become brides before the king, that he may choose such as are agreeable to him." When the plebeians of the Etruscan city of Volsinii rebelled against the aristocrats in 280 BC, "They took their wives for themselves and placed the daughters of

This specific risk, also called unsystematic, can be nulled out of a portfolio through diversification. Pooling multiple securities means the specific risks cancel out. In complete markets , there is no compensation for idiosyncratic risk—that is, a security's idiosyncratic risk does not matter for its price. For instance, in

The line was cut from the film, but the geis remains in place as the curse of the Flying Dutchman . With the help of Jack Sparrow , Will Turner stabs the heart and becomes the new captain of the Dutchman . Geasa are widely used in Charles Stross 's Laundry Files series, especially employed by The Laundry (Britain's secret government agency tasked with protecting

825-404: Is high. Type B reactions are most commonly immunological (e.g. penicillin allergy). The word is used for the personal way a given individual reacts, perceives and experiences: a certain dish made of meat may cause nostalgic memories in one person and disgust in another. These reactions are called idiosyncratic . In portfolio theory , risks of price changes due to the unique circumstances of

Idiosyncrasy defined the way physicians conceived diseases in the 19th century. They considered each disease as a unique condition, related to each patient. This understanding began to change in the 1870s, when discoveries made by researchers in Europe permitted

There are many references to
990-721: The Recueil d'arrêts notables des cours souveraines de France of the French lawyer and author Jean Papon . The French writer Antoine du Verdier also commented on it in 1577. The French philosopher Montesquieu referred to the practice in The Spirit of the Laws (1748), saying that it had been enforced in France over three nights. Voltaire mentioned the practice in his Dictionnaire philosophique , published in 1764. He wrote
1045-644: The droit du seigneur . However, according to British scholar W. D. Howarth, the Catholic Church at some times prohibited consummation of a marriage on the first night. The payment was for an indulgence from the church to waive this prohibition. In the Wooing of Emer in Irish mythology the King Conchobar has the droit du seigneur over all marriages of his subjects. He is afraid of Cú Chulainn 's reaction if he exercises it in this case, but
1100-542: The geas placed on him by his mother, he refuses to identify himself, which leads to his own father, Cú Chulainn, killing him in single combat using the Gáe Bulg before recognising too late who he is. He then introduces his dying son to the men of Ulster as a fitting hero. A geas might appear beneficial by involving a prophecy that a person would die in a particular way so bizarre that they could then avoid their fate for many years. As with Conaire Mór , though, in
1155-564: The Encyclopædia Britannica and the Larousse encyclopedias dramatically changed their opinion on the topic, moving from acceptance to rejection of the historical veracity of the idea. French writer Louis Veuillot wrote a book in 1854 disputing its existence. After an exhaustive historical study, German jurist Karl Schmidt concluded in 1881 that it was a scholarly misconception. After Schmidt, many of those who believed in

#17327838981201210-458: The Celtic scholar Whitley Stokes said that the existence of the practice was "evidenced though not proved" to have existed in Ireland. In 1930, Scottish legal scholar Hector McKechnie concluded, based on historical evidence, that the practice had existed in Scotland in early times. Italian scholar Paolo Mantegazza , in his 1935 book The Sexual Relations of Mankind , said that while not a law, it
1265-616: The Geis of the king. Whether this right actually existed and was exercised by the Celts is not attested outside the sagas. It is similar to the droit du seigneur of feudal Europe. Considerable similarity exists between the Goidelic geasa and the Brythonic tynged . This is not surprising given the close origins of many of the variants of Celtic mythology . For example,
1320-523: The Jurchens. A historian has speculated that this could mean that in Jurchen upper classes, only a husband had the right to his married wife while among lower class Jurchens, unmarried girls' virginity and sleeping with Liao Khitan men did not matter and did not impede their ability to marry later. The Jurchens' sexual habits and mores seemed lax to Han Chinese , such as marrying with an in-law, which
1375-743: The Liao envoys who had sex with the girls. Song envoys among the Jin were similarly entertained by singing girls in Guide, Henan. Although the Liao Khitan had superior power over the Jurchens when ruling them, there is no evidence that guest prostitution of unmarried Jurchen girls to Khitan men was hated or resented by the Jurchens. It was only when the Liao Khitan forced aristocratic Jurchen families to give up their beautiful wives as guest prostitutes to Liao Khitan messengers that this stirred resentment and anger by
1430-515: The Scottish historian Hector Boece wrote that the "right" had existed in Scotland until abolished by Malcolm III ( r. 1058–93) under the influence of his wife, Margaret (later St Margaret of Scotland ). The payment of merchet was instituted in its place. Boece attributed the law to a legendary king , Ewen or Evenus III. The modern French scholar Alain Boureau says that Boece probably invented King Ewen, but he views this as mythology, not as
1485-406: The Scottish legal scholar David Maxwell Walker , instances have been recorded of the jus primæ noctis being claimed up to the 18th century. Walker concluded that it is possible that the jus existed as a custom in Scotland, dependent on the attitude of the king, and survived longer in remote regions. After their travels in Scotland in 1773, Samuel Johnson and James Boswell documented
1540-455: The Welsh hero Lleu Llaw Gyffes (in one version of his story) was destined to die neither "during the day or night, nor indoors or outdoors, neither riding nor walking, not clothed and not naked, nor by any weapon lawfully made." He was safe until his wife, Blodeuwedd , learning of these foretold conditions, convinced him to show her how he could theoretically be stepping out of a river onto

The term idiosyncratic drug reaction denotes an aberrant or bizarre reaction or hypersensitivity to a substance, without connection to the pharmacology of the drug. It is what is known as a Type B reaction. Type B reactions have the following characteristics: they are usually unpredictable, might not be picked up by toxicological screening, not necessarily dose-related, incidence and morbidity low but mortality
1650-445: The classic version of the "right of first night" with money payment as an alternative. According to Howarth, this suggests that droit du seigneur was a familiar notion to people at that time, which he traces back to Boece. In modern times, Zaire 's president Mobutu Sese Seko appropriated the droit de seigneur when traveling around the country, where local chiefs offered him virgins. The term has also been used to describe
1705-469: The coupling with favor. This is because the girl might conceive the chief's child and be allowed to keep it. Scholars in the 19th and 20th centuries gave the historical basis of the "right of first night" a good deal of attention. Historians David M. Walker and Hector McKechnie wrote that the right might have existed in medieval Europe, but other historians have concluded that it is a myth, and that all references to it are from later periods. Over time,

1760-526: The custom had existed in Scotland, but not in England. The English jurist William Blackstone cited Boece's statement in his Commentaries on the Laws of England (1765–1769), while similarly noting that the custom had never existed in England. In 1776, the Scottish jurist David Dalrymple disputed the existence of the custom, arguing Boece's account was purely legendary, but his position was often seen as based on Scottish patriotism . However, according to

They paralleled it with that custom of Borough English , suggesting that the English custom favored the youngest son because the paternity of the eldest son was doubtful.

1870-446: The custom throughout the centuries. The French expression droit du seigneur translates as "right of the lord", but modern French usage prefers droit de jambage ( French: [dʁwa d(ə) ʒɑ̃baʒ] , from jambe , 'leg') or, more commonly, droit de cuissage ( French: [dʁwa d(ə) kɥisaʒ] , from cuisse , 'thigh'). The term is often used synonymously with jus primae noctis , Latin for "right of
1925-430: The doom of heroes comes about due to their violation of their geas either by accident or by having multiple geasa , which then come into conflict. For instance, Cú Chulainn has a geas to never eat dog meat, and he is also bound by a geas to eat any food offered to him by a woman. When a hag offers him dog meat, he has no way to emerge from the situation unscathed; this leads to his death. In some cases,

2035-520: The existence of the custom based their opinions on anthropological studies of tribal societies, though according to W. D. Howarth, this was a misguided argument because of the disparity between the tribal societies and medieval European society. In The Origin of the Family, Private Property and the State in 1884, socialist Friedrich Engels argued it was real and had an anthropological origin. In 1910,

In the Epic of Gilgamesh , Gilgamesh is described as having practiced a similar custom: "He is king, he does whatever he wants... takes the girl from her mother and uses her, the warrior's daughter, the young man's bride."

Idiosyncrasy is sometimes used as a synonym for eccentricity , as these terms "are not always clearly distinguished when they denote an act, a practice, or a characteristic that impresses the observer as strange or singular."

Aoife imposed three geasa on Connla , her son with Cú Chulainn: he cannot turn back once he starts his journey; he must not refuse a challenge; and he must never tell anyone his name. She then sent Connla, aged seven, to seek out his father, but he was a child of such extraordinary skill that he was seen as a threat after having defeated all Ulster heroes who met him. Because of

Prohibitions and taboos similar to geasa are also found in more recent English literature , though they are not described as geasa in those texts.

American historian Vern Bullough suggested that this illustrates that such behaviour was commonplace in the period, and that the "legend [of droit du seigneur ] reflected the reality".

In modern Scottish Gaelic , the spelling has evolved in a slightly different direction (nom. sg. geas /kʲes/ , nom. pl. geasan , gen. sg. geis or geasa ). It has also been borrowed into English in both forms (sg. geas or geis /ɡɛʃ/ or /ˈɡi.əʃ/ , pl. geasa )). A geas can be compared with
