Problem: Background: Celtic art is associated with the peoples known as Celts; those who spoke the Celtic languages in Europe from pre-history through to the modern period, as well as the art of ancient peoples whose language is uncertain, but have cultural and stylistic similarities with speakers of Celtic languages. Celtic art is a difficult term to define, covering a huge expanse of time, geography and cultures. A case has been made for artistic continuity in Europe from the Bronze Age, and indeed the preceding Neolithic age; however archaeologists generally use "Celtic" to refer to the culture of the European Iron Age from around 1000 BC onwards, until the conquest by the Roman Empire of most of the territory concerned, and art historians typically begin to talk about "Celtic art" only from the La Tene period (broadly 5th to 1st centuries BC) onwards. Early Celtic art is another term used for this period, stretching in Britain to about 150 AD.
Context: The ancient peoples now called "Celts" spoke a group of languages that had a common origin in the Indo-European language known as Common Celtic or Proto-Celtic. This shared linguistic origin was once widely accepted by scholars to indicate peoples with a common genetic origin in southwest Europe, who had spread their culture by emigration and invasion. Archaeologists identified various cultural traits of these peoples, including styles of art, and traced the culture to the earlier Hallstatt culture and La Tene culture. More recent genetic studies have indicated that various Celtic groups do not all have shared ancestry, and have suggested a diffusion and spread of the culture without necessarily involving significant movement of peoples. The extent to which "Celtic" language, culture and genetics coincided and interacted during prehistoric periods remains very uncertain and controversial. Celtic art is associated with the peoples known as Celts; those who spoke the Celtic languages in Europe from pre-history through to the modern period, as well as the art of ancient peoples whose language is uncertain, but have cultural and stylistic similarities with speakers of Celtic languages. The term "Celt" was used in classical times as a synonym for the Gauls (Keltoi, Celtae). Its English form is modern, attested from 1607. In the late 17th century the work of scholars such as Edward Lhuyd brought academic attention to the historic links between Gaulish and the Brythonic--and Goidelic--speaking peoples, from which point the term was applied not just to continental Celts but those in Britain and Ireland. Then in the 18th century the interest in "primitivism", which led to the idea of the "noble savage", brought a wave of enthusiasm for all things Celtic and Druidic. The "Irish revival" came after the Catholic Emancipation Act of 1829 as a conscious attempt to demonstrate an Irish national identity, and with its counterpart in other countries subsequently became the "Celtic Revival".

Problem: Background: Van Sant was born in Louisville, Kentucky, the son of Betty (nee Seay) and Gus Green Van Sant, Sr; Gus's father was a clothing manufacturer and traveling salesman who rapidly worked his way into middle class prosperity, holding executive marketing positions that included being president of the White Stag Manufacturing Company's Apparel Operation. As a result of his father's job, the family moved continually during Van Sant's childhood. His paternal family is of partial Dutch origin; the name "Van Sant" is derived from the Dutch name "Van Zandt".
Context: After spending time in Europe, Van Sant went to Los Angeles in 1976. He secured a job as a production assistant to writer/director Ken Shapiro, with whom he developed a few ideas, none of which came to fruition. In 1981, Van Sant made Alice in Hollywood, a film about a naive young actress who goes to Hollywood and abandons her ideals. It was never released. During this period, Van Sant began to spend time observing the denizens of the more down-and-out sections of Hollywood Boulevard. He became fascinated by the existence of this marginalized section of L.A.'s population, especially in context with the more ordinary, prosperous world that surrounded them. Van Sant would repeatedly focus his work on those existing on society's fringes, making his feature film directorial debut Mala Noche. It was made two years after Van Sant went to New York to work in an advertising agency. He saved $20,000 during his tenure there, enabling him to finance the majority of his tale of doomed love between a gay liquor store clerk and a Mexican immigrant. The film, which was taken from Portland street writer Walt Curtis' semi-autobiographical novella, featured some of the director's hallmarks, notably an unfulfilled romanticism, a dry sense of the absurd, and the refusal to treat homosexuality as something deserving of judgment. Unlike many gay filmmakers, Van Sant--who had long been openly gay--declined to use same-sex relationships as fodder for overtly political statements, although such relationships would frequently appear in his films. Shot in black-and-white, the film earned Van Sant almost overnight acclaim on the festival circuit, with the Los Angeles Times naming it the year's Best Independent Film. The film's success attracted Hollywood interest, and Van Sant was briefly courted by Universal; the courtship ended after Van Sant pitched a series of project ideas (including what would later become Drugstore Cowboy and My Own Private Idaho) that the studio declined to take interest in. Van Sant moved back to Portland, Oregon, where he set up house and began giving life to the ideas rejected by Universal. He directed Drugstore Cowboy about four drug addicts robbing pharmacies to support their habit. The film met with great critical success and revived the career of Matt Dillon.
