The Cochno Stone in Clydebank is now one of the most important prehistoric rock-art sites in Scotland. This talk by Kenny Brophy will recount its colourful history, from antiquarian discovery, to being painted by Ludovic Mann, to vandalism and burial. The story will then be brought up to date with details of the excavation of the Cochno Stone in 2016 and provide updates on analysis of the data gathered during this fieldwork.
