Question: Gaelic Ireland (Irish: Eire Ghaidhealach) was the Gaelic political and social order, and associated culture, that existed in Ireland from the prehistoric era until the early 17th century. Before the Norman invasion of 1169, Gaelic Ireland comprised the whole island. Thereafter, it comprised that part of the country not under foreign dominion at a given time. For most of its history, Gaelic Ireland was a "patchwork" hierarchy of territories ruled by a hierarchy of kings or chiefs, who were elected through tanistry.

Throughout the Middle Ages, the common clothing amongst the Gaelic Irish consisted of a brat (a woollen semi circular cloak) worn over a leine (a loose-fitting, long-sleeved tunic made of linen). For men the leine reached to their ankles but was hitched up by means of a crios (pronounced 'kriss') which was a type of woven belt. The leine was hitched up to knee level. (Gaelicattire.com) Women wore the leine at full length. Men sometimes wore tight-fitting trews (Gaelic triubhas) but otherwise went bare-legged. The brat was simply thrown over both shoulders or sometimes over only one. Occasionally the brat was fastened with a dealg (brooch), with men usually wearing the dealg at their shoulders and women at their chests. The ionar (a short, tight-fitting jacket) became popular later on. In Topographia Hibernica, written during the 1180s, Gerald de Barri wrote that the Irish commonly wore hoods at that time (perhaps forming part of the brat), while Edmund Spenser wrote in the 1580s that the brat was (in general) their main item of clothing. Gaelic clothing does not appear to have been influenced by outside styles.  Women invariably grew their hair long and, as in other European cultures, this custom was also common among the men. It is said that the Gaelic Irish took great pride in their long hair--for example, a person could be forced to pay the heavy fine of two cows for shaving a man's head against his will. For women, very long hair was seen as a mark of beauty. Sometimes, wealthy men and women would braid their hair and fasten hollow golden balls to the braids. Another style that was popular among some medieval Gaelic men was the glib (short all over except for a long, thick lock of hair towards the front of the head). A band or ribbon around the forehead was the typical way of holding one's hair in place. For the wealthy, this band was often a thin and flexible band of burnished gold, silver or findruine. When the Anglo-Normans and the English colonized Ireland, hair length came to signify one's allegiance. Irishmen who cut their hair short were deemed to be forsaking their Irish heritage. Likewise, English colonists who grew their hair long at the back were deemed to be giving in to the Irish life.  Gaelic men typically wore a beard and mustache, and it was often seen as dishonourable for a Gaelic man to have no facial hair. Beard styles varied - the long forked beard and the rectangular Mesopotamian-style beard were fashionable at times.

Problem: Kidder, one of five children, was born in Yellowknife, Northwest Territories, the daughter of Jocelyn Mary "Jill" (nee Wilson), a history teacher, and Kendall Kidder, an explosives expert and engineer. Kidder also spent time growing up in Labrador City, Newfoundland and Labrador. Her mother was from British Columbia, Canada, and her father was from New Mexico, United States. She is of Welsh and English descent.

In 1975, Kidder was cast in a lead role in The Great Waldo Pepper opposite Robert Redford, she also appeared in The Reincarnation of Peter Proud and 92 in the Shade (1975) with Peter Fonda, all of which established her as a commercially viable leading lady. Kidder famously married the director of 92 in the Shade, Thomas McGuane. She appeared on the March 9, 1975 edition of The American Sportsman, learning how to hang glide with her providing the narration and a remote microphone recording her reactions in flight; the segment concluded with Kidder doing solos soaring amid the Wyoming Rockies.  After taking a break from acting after the birth of her daughter in 1976, Kidder sought to return to making films in the late 1970s. After doing a reading of Lois Lane for the 1978 superhero film Superman: The Movie, Kidder was flown to England by Richard Donner for screen-tests. Donner ultimately cast Kidder in the role, which would become her most iconic. Filming took over a year, and the film was released during Christmas 1978, to major commercial success. Kidder won a Saturn Award for best actress for her performance in the film. Kidder publicly disagreed with the decision of producers Alexander Salkind and Ilya Salkind to replace Richard Donner as director for Superman II (1980). It was reported that as a result, Kidder's role in Superman III (1983) consisted of less than five minutes of footage, though the producers have denied this in DVD commentaries. Her role in Superman IV: The Quest for Peace (1987) was more substantial.  Kidder's performance as Kathy Lutz in the 1979 summer release of The Amityville Horror further cemented her status as one of Hollywood's leading ladies. Though it received mixed reviews from critics, The Amityville Horror was a major commercial success, grossing over $86 million in the United States. Janet Maslin of The New York Times, though giving the film a mixed review, said Kidder "stubbornly remains the bright-eyed life of the party [in the film]." In retrospect, Kidder called the film "a piece of shit." The same year, Kidder hosted an episode of the American sketch comedy TV show Saturday Night Live.
