Correspondence addressed to the antiquary Sir John Clerk, 2nd baronet of Penicuik, Midlothian, allows us to document the initial recording in 1723 of Roman inscriptions and relief sculpture observed at several forts along the line of the Antonine Wall between the Forth and Clyde, and the arrangements put in place to transport them to his home at Penicuik House. Particularly valuable is a series of drawings, which are sometimes our only visual record of the stones.
