Hadrian's Wall was constructed by the Roman Legions based in Britain.Each cohort had to construct 80 yard sections.Proud of their achievements they left inscriptions along their section of Wall,letting the World know,who built what.Most of these inscriptions are safely kept in the various Museums along Hadrian's Wall.But,every now and then,an inscription turns up,reused in a building.This inscription,is on plain view at Willowford farm,right on the line of Hadrian's Wall.It demonstrates the universality of the Roman Army and thus of the Roman Empire.Here,on the most northerly boundary of that vast Empire,is an inscription,abbreviated in the Roman tradition(all Roman inscriptions were abbreviated in an accepted fashion).It reads"from the fifth cohort,the century of GELLIVS PHILIPPUS(BUILT THIS)".A man,most likely,from modern Greece,came to this far flung spot and recorded his work,for posterity.
