The vanished menhir of St Mabyn has been noticed (p. 42 _supra_), but, before leaving the English megaliths, we ought to glance at the smallest cromlech in Cornwall, that of Duloe, which is situated near Duloe church. Its longer diameter is 39 feet, and its shorter, 37 feet, so that the cromlech is slightly elliptical. The “circle” contains seven standing stones, and one fallen or broken stone. One of the pillars, which are very unshapely, is 9 feet in height. The finding of charcoal, together with a cinerary urn enclosing bones, near one of the pillars, is sufficient to show the sepulchral character of the circle[136]. Cornwall should indeed prove the touchstone of our theory, and I believe that both Cornwall and Devon would stand the test well, could we recall the witnesses. But these, sad to relate, are for the most part gone. Here a gatepost, there a tombstone, and yonder the hearth of a cottage, warn us not to expect the impossible. Sir Norman Lockyer, in his work on Stonehenge, asserts that many churches have been built on the sites of circles and menhirs, but he proffers no actual examples[137]. He gives, however, numerous instances from Cornwall, Ireland, and Scotland, of the juxtaposition of megaliths and sacred wells. Now, it will be shown in the next chapter, that churches were frequently built in proximity to holy wells, so that we have a triple relationship. Sir Norman Lockyer’s informant doubtless knew of other examples of church-megalith sites than those which have been adduced[138]. Such sites are said to be not uncommon in Wales. The church at Yspytty Kenwyn (or Cynfyn), near the Devil’s Bridge, in Cardiganshire, had the circle of stones built, at intervals, into the churchyard wall. There were also stone pillars at the Eastern entrance to the church, just as they are sometimes found near stone-circles. Large megaliths are also recorded from the churches of Tregaron, in Cardiganshire, and Llanwrthwl, in Brecon[139]. Cordiner, an eighteenth century writer, asserts that Benachie church, Aberdeenshire, is built within a stone-circle, and that the practice of thus building was not infrequent in that country. And Mr W. G. Wood-Martin has recorded at least two cromlechs in Irish churchyards[140].
