Dragon of Wantley (i.e. Warncliff, in Yorkshire).
A monster slain by More, of More Hall, who procured a suit of armour studded with spikes; and, proceeding to the well where the dragou had his lair, kicked it in the mouth, where alone it was vulnerable. Dr. Percy says this dragon was an overgrown, rascally attorney, who cheated some children of their estate, but was made to disgorge by a gentleman named More, who went against him, armed with the spikes of the law, after which the dragon attorney died of vexation.
