 Benjamin Hudson argued that the tale was the basis for the account given by Gerald of Wales in the "Instructions for Princes" and by the author of the "Prophecy of Berchán".In this story, the Scots invite the Pictish nobles to their banquet hall for a feast; the Scots however prearranged for the banquet seats to sit on top of a pit, and engineered the set-up in such a way that removing a pin would drop those seated into the pit underneath.Gerald's tale did not feature Kenneth MacAlpin or Drust.
