cartographic

1715-1716.
This map of Perth shows the defensive fortifications thrown up by the armies of James Francis Edward Stuart, after their capture of the town early in the 1715 rising. It also show the seventeenth century Cromwellian citadel. The map was done by Louis Petit, after the failure of the rising, late in 1715, and the recapture of Perth by government forces. There is another map of these fortifications of the same date, by one of Petit's team, Capt. William Horneck, at shelfmark MS.1647.Z.03/02a (copies at shelfmarks MS.1647.Z.03/02b and MS.1647.Z.03/02c.) As a result of the capture of the town, Petit proposed the building of a new fort, which was never taken up (plan at shelfmark MS.1647.Z.03/01a, copy at shelfmark MS.1647.Z.03/01b).
