Traditional Accounts
The traditions surrounding Endellion are drawn from later Cornish legend rather than contemporary record. The best-known relates that she subsisted at Trentinney solely on the milk of a single cow and the water of two nearby wells. When the cow strayed onto the land of the local lord and was killed by him, the nobleman was in turn slain by Endellion's reputed godfather, said in the legend to be King Arthur; Endellion is then said to have restored the lord to life, unwilling that a killing should be done on her account.
A further tradition concerns her burial: according to her own instructions her body was laid on a cart yoked to two young untended bullocks, which were allowed to draw the bier unguided until they halted on a hilltop, marking the place of her grave. The church of St Endellion was afterward raised on that spot.
