Greg Hill’s poem ‘Gutuater’ led me to the section on the underground shrine of the Chartres ‘magician’, dated ‘to the second century AD’, in Miranda Aldhouse-Green’s Sacred Britannia (2018). In 2005, during excavations for a car park in the centre of Chartres the construction workers found a ‘basement shrine’ accessed by ‘a wooden ladder and ‘a cache of sacred material, including pottery vessels, oil-lamps and a broad-bladed knife, of the kind used in killing sacrificial animals.’
