Charles S. T. Calder was a Scottish archaeologist who undertook extensive explorations from the 1920s to 1950s. He is best known for his explorations of Neolithic cairns and buildings in Shetland in the 1940s and 1950s, although his contribution to the investigative work and publications of RCAHMS during a period of over 40 years service cannot be overstated.
From the mid-1920s through to the outbreak of World War II, Calder was active in the resurgence of studies of Neolithic sites in Scotland as Investigator in the RCAHMS, as were V. Gordon Childe, Walter Gordon Grant and J Graham Callander, Keeper of the National Museum of Antiquities. By 1931 he had become an Associate of the Edinburgh Architectural Association. In the 1930s he excavated two Iron Age roundhouses on the Calf of Eday, with the help of local men. He excavated other sites on Eday and the Calf of Eday in the late 1930s and prepared the first complete description of the Dwarfie Stane on Hoy. World War II began in 1939. In 1940 Calder conducted an emergency excavation of a broch in Caithness before it was destroyed to make way for the new airport of RAF Skitten. He found a saddle quern, grain rubbers, dishes, knocking stones, pivot stones, anvils, tether stones, pot lids, pounders and smoothing stones, a pestle and a whorl. There were also fragments of circular querns dating after the Roman period. On 14 January 1941 it was noted that Calder had relinquished his rank as Lieutenant on enlistment into the ranks. The war ended in 1945. In 1949 it was noted that he had retired from the Territorial Army with the rank of Lieutenant. In 1946 Calder was appointed senior investigator by the RCAHMS, and in 1951 principal investigator. He found, excavated and recorded many Neolithic sites in Shetland including the Stanydale Temple on Mainland, Shetland, houses and cairns in Whalsay, and the Sae Breck broch in Esha Ness. Calder explored the Stanydale site in 1949. He thought it was a temple, and the name "Stanydale Temple" has stuck. He thought the design originated from Mediterranean temples. He saw a strong resemblance to these structures, saying, "it is almost impossible not to assume that the Maltese temples are the prototypes from which Stanydale is derived and which solve the question of its purpose." He excavated the Standing Stones of Yoxie and the nearby Benie Hoose in Whalsay, interpreting the Yoxie structure as a temple similar to Stanydale and Benie Hoose as a house that may have been used by the priests. Calder worked in a period before the Radiocarbon dating technique had been discovered. He was forced to rely on comparison with other buildings, sometimes distant, to estimate ages. His comparison of the Staneydale Temple to Maltese structures, then thought to be from the Bronze Age, is an example. With more accurate tools at the archaeologist's disposal, this is no longer considered a valid approach. Calder retired in 1960. He died in December 1972.
