Thus the two earliest versions of this story both put the onus for building the bridge on Robert the Bruce, and neither mention involvement by Bishop Cheyne. This story has been repeated a number of times over the centuries often with only minor changes. In 1780 Francis Douglas wrote that it "is said to have been built by Henry Cheyne, bishop of Aberdeen, about the year 1290, or by King Robert the Bruce, who perhaps completed what the bishop had begun." In the 19th century Camden wrote that "it was projected by Bishop Henry Cheyne … and built at his expense". In the 20th century Alexander Keith tells all elements of the story: that it was started by Bruce or Cheyne, but certainly completed by the former. He favours the Bruce version citing Hay and Boece as his evidence. The story about the involvement of Cementarius is an entirely new one, and seems to be no older than the 20th century. It was perhaps first stated by W. Douglas Simpson.
