For English archaeologist John Evans, who excavated prehistoric Maltese sites during the late 1940s and 1950s, the Mediterranean islands were "laboratories for the study of culture processes." On Malta the laboratory experiment took an unusual turn. Its Neolithic inhabitants began, like other Neolithic peoples, as simple farmers and herders but ended up building immense stone temples and digging equally immense subterranean sepulchres. Why this happened and why the temple builders abruptly stopped constructing temples after a millennium defy easy answers. An Anglo-Maltese project directed by David Trump of the University of Cambridge, Simon Stoddart and Caroline Malone (then of the University of Bristol), and the University of Malta's Anthony Bonanno has done much to sort out the evidence. Working on Gozo, they excavated Neolithic huts at Ghajnsielem in 1987 and underground burials, yielding hundreds of thousands of human bones, at Xaghra from 1988 to 1994. Using the new evidence and that from earlier studies, the Gozo Project archaeologists have devised a theory about how the temple building culture may have risen and collapsed. They see a shift from an early, egalitarian society, to a hierarchical one marked initially by competition among familes in trade with Sicily, followed by competition among chiefdoms in constructing temples for ritual use. Preoccupation with the temples, increasing population, greater agricultural uncertainty stemming from erosion, and declining links to Sicily left the culture on the brink of collapse. In time the temples were abandoned; the fate of their builders remains unknown.
