Charles Vallancey

General Charles Vallancey FRS (6 April 1731 – 8 August 1812) was a British military surveyor sent to Ireland. He remained there and became an authority on Irish antiquities. Some of his theories would be rejected today, but his drawings, for example, were painstakingly accurate compared to existent artefacts. Other drawings, such as his diagram of the banquet hall at Tara, and the lost crown of the High King of Ireland, are unverifiable, as the manuscripts and material he used no longer exist.
