argued that cultural diversity underlay the process of humanisation. The book received few reviews, including one produced by Edmund Leach for Nature which was highly critical, claiming that Clark's functionalist and culturally evolutionary approach was outdated. He then produced a sequel, Symbols of Excellence, which allowed him to discuss his interest in art; it was published by Cambridge University Press in 1986. In 1989, Clark's Prehistory at Cambridge and Beyond was published, a work that was part-biography and part-history of archaeology, discussing the broad diaspora of Cambridge-trained archaeologists. Clark's final book, Space, Time, and Man: A Prehistorian's View, was published by Cambridge University Press in 1992. The book dealt with concepts of time and place throughout the ages and received few reviews on publication. According to Fagan, Clark's later books were "based on the values of an earlier time and reflect his profound conservatism", perhaps explaining why they received so little attention. In his final years, Clark continued to receive recognition for his achievements. The Netherlands Foundation awarded him the Erasmus Prize in 1990. He divided the £100,000 prize money between the British Academy and the Prehistoric Society, allowing both to establish their own prizes. In 1992, the British state then awarded him a knighthood. While on a cruise in the eastern Mediterranean with his wife, Clark suffered a serious stroke in June 1995, requiring a return home. There, he died in Cambridge on 12 September 1995. A memorial service was held at Little St Mary's, Cambridge. One of his fellow staff members at Cambridge, John Coles, was appointed literary executor of his books and papers. Archaeological approach According to Fagan, Clark was "more concerned with what happened [in the past] rather than how or why." The archaeologist John Mulvaney stated that, in contrast to the tendency of Childe and other archaeologists to focus on artefact typologies, Clark's "vibrant world embraced landscape, economy and social themes, not simply labelled artefacts". This was reflected in the changing definitions of archaeology that Clark used; in 1927 he claimed that archaeology was "the study of past distribution of culture-traits in time and space, and of the factors governing their distribution", while in 1939 he referred to it as "the study of how men lived in the past". Clark was fascinated by prehistoric subsistence and social patterns. His approach to prehistory was rooted in the notion that the human race was biologically united and
