Backyard pendulum saw sliced: Bronze Age mystery
Researcher’s swinging blade offers glimpse into how ancient Mycenaeans built palaces
ENIGMATIC ENGINEERING An ancient sculpture known as the Lion Gate relief contains marks in a column (center of image) that may have been made by a pendulum saw. The lions, now headless, stood above the main entrance to the citadel of Mycenae, in what is now Greece.
LULU AND ISABELLE/SHUTTERSTOCK
Nicholas Blackwell and his father went to a hardware store about three years ago seeking parts for a mystery device from the past. They carefully selected wood and other materials to assemble a stonecutting pendulum that, if Blackwell is right, resembles contraptions once used to build majestic Bronze Age palaces.
With no ancient drawings or blueprints of the tool for guidance, the two men relied on their combined knowledge of archaeology and construction.
Blackwell, an archaeologist at Indiana University Bloomington, had the necessary Bronze Age background. His father, George, brought construction cred to the project. Blackwell grew up watching George, a plumber who owned his own business, fix and build stuff around the house. By high school, the younger Blackwell worked summers helping his dad install heating systems and plumbing at construction sites. The menial tasks Nicholas took on, such as measuring and cutting pipes, were not his idea of fun./.../
