The initial Roman occupation of central Scotland was achieved relatively peacefully, perhaps with native consent, and it lasted up to 15 years - much longer than previously thought, according to new research.
Recent evidence from the 'Gask frontier' - the earliest land frontier in the Roman Empire - indicates that it was established in the 70s AD rather than the mid-80s, before being abandoned sometime after 86. The frontier consists of a network of forts, fortlets and watchtowers between Stirling and Perth centred on the legionary fortress of Inchtuthil. Its purpose was to control the main route between southern Scotland and the north, where the A9 road runs today.
In a series of excavations since 1995, the Liverpool University-based Roman Gask Project has produced large quantities of pottery and glass that clearly date to the 70s. Researchers have found that many sites saw major structural changes, suggesting lengthy occupation. At Cardean fort, for example, the granaries were rebuilt and the early barrack block was replaced by a possible stable. Every watchtower on the frontier was rebuilt at least once.
In the traditional view, the frontier was established in the 80s through the campaigns of the governor Agricola. The theory was based largely on the writings of Tacitus, Agricola's son-in-law. According to Birgitta Hoffmann, deputy director of the project, the new evidence suggests the founder was more likely Petillius Cerialis, general and diplomat, and governor in 71-73/4.
He appears to have been welcomed by the native population. Pollen evidence from settlements in the area shows no agricultural decline from the 70s - as would be expected if occupation had been achieved through conquest, as many native farmers would have been killed. Instead, it shows the intensification of grazing, with pastures supporting bigger herds.
Evidence from the latest season's work at Coldoch, two miles from the Roman fort of Doune, suggests the natives may have started to grow wheat - a crop not generally grown in Iron Age Scotland - to trade to the Roman army and its camp followers, who may have numbered as many as 20,000. Fragments of 1st century Roman glass at the settlement proves there was contact between incomers and natives.
'With the bigger cattle herds and possible evidence of wheat cultivation, it looks very much like the Romans were providing a market for the local population,' Dr Hoffmann said.
A book by project director David Woolliscroft, 'The Roman Frontier on the Gask Ridge, Perth & Kinross' was published last year by BAR (vol 335).
