Albany brought a number of foreign craftsmen to work in Scotland in 1515. 'Johne Belloun,' Frenchmen or 'Master Johne Carvour' worked on new windows and doors for the Palace of Holyroodhouse, and repaired a number of spears and pikes. An Italian called 'Auld Julian' made 6000 bricks at Tranent to be used for building a furnace at the armoury in Edinburgh Castle, where the master gun-founder Robert Borthwick was joined by the Frenchmen, 'Johne Bukkat' and his apprentice 'Perys.' Two of the cannons they made, marked with the Duke's arms and listed as "quarter-falcons," were still in use at Edinburgh Castle in 1579.
