London itself might not be expected to yield much testimony to this romantic portion of our study. Yet several London churches had their wells. Hard by St Giles’s churchyard there was formerly a pool, and near Clerkenwell church was the celebrated “Clerkes’ Well” which is believed to have given the parish its name. At the Skinners’ Well “the skinners of London held there certain plays yearly, played of Holy Scripture.” St Clement’s Well, Holywell Street, Strand, near the parish church of the same name, was “fair curbed with hard stone, kept clean for common use, and [was] always full[258].” Rapidly skimming over the Eastern counties, we find that the Rev. G. S. Tyack, who has assiduously collected examples of holy wells, records an example from the West end of East Dereham graveyard, in Norfolk. In Yorkshire alone, Mr Tyack claims seventeen wells, though whether all of these are in the neighbourhood of churches, he does not say[259]. Lincolnshire contributes several instances; one only need be noted. Caistor church, in that county, previously mentioned (p. 12 _supra_) as standing within the confines of a Roman camp, was built near three or four springs. One of these, a “healing” spring, issued from the side of the churchyard. This example may be compared with that of Whitestaunton; in each case, there seems to have been a desire on the part of both Roman general and Christian architect to exploit the reputation previously gained by the waters. Here our enumeration must come to an end; for fuller details the reader may be referred to well-known works[260]. But if we forget that worship may be conducted under the open sky as well as under a roof of wood or stone, and if we overlook the fact that natural features, not less than stately fanes, were dedicated to patron saints, we shall miss much of the evidence which has fortunately been bequeathed to us.
