The Rev. William Slater Calverley (1847–1898) was an unassuming rural English vicar who through diligent study and painstaking scrutiny became an extraordinary amateur antiquarian. Although born in Leicestershire, Calverley claimed his fame through interpreting the carved sculptured relics that he and others found in Cumberland churchyards. He made intricate drawings, corresponded with academic authorities, and gave his own interpretations, which he then relayed to a wider audience. Calverley later produced in intricate detail a life-sized reproduction of the famous Gosforth Cross, which now stands in Aspatria churchyard.

The Gosforth Cross is a large stone monument in St Mary's churchyard at Gosforth in the English county of Cumbria, dating to the first half of the 10th century AD. Formerly part of the kingdom of Northumbria, the area was settled by Scandinavians some time in either the 9th or 10th century. It has gained reputation for its combination of Christian symbols with Nordic symbols, being a tangible piece of evidence of the impact of the Christianization of Scandinavia.
