14 I wish to thank Professor Anthony Birley for his comments on the original idea and supplying other information. The discrepancy between the use of the title ‘P P’ and the Trib. Pot. dates on the Thurmaston and Llanfairfechan milestones has been noted by several other scholars, but this is the first time that the evidence has actually been collected in one place and compared with other inscriptions throughout the empire. I also wish to thank my supervisor, Charles Daniels, and Drs Stephen Johnson and Derek Welsby for commenting on a draft of this note, although neither they nor Professor Birley are to be considered responsible for the final conclusions offered here.
15 Breeze, D. J. and Dobson, B., Hadrian's Wall (1978), 55Google Scholar, favour a date of A.D. 122 for the commencement of building on Hadrian's Wall, although there does remain the possibility that work had started earlier, under Falco, and that only the completion of the mural barrier and the fort decision were the responsibility of Nepos; cf.
