Giant statue of Roman emperor once stood in southern Scotland

For more than two hundred years, the lower leg of a gilded bronze statue — complete with a booted foot and dated to the 140s AD — sat in a charter room at Dalkeith House, catalogued as loot carried north from York by Scottish raiders. The artifact, recovered from a bog at Milsington near Hawick, has been reinterpreted through a wider study of Roman frontier statue fragments. Researchers at National Museums Scotland now argue it belonged to a larger-than-life equestrian monument of Emperor Antoninus Pius, erected in the Scottish Borders around AD 140 to commemorate the conquest of southern Scotland.

The evidence turns on how the leg was detached. The top of the fragment shows no cut marks; it remains exactly as cast, and the absence of gilding around the knee indicates it was once covered by a sculpted tunic or cloak. That careful removal, not brutal hacking, matches a pattern seen elsewhere when Roman forces abandoned the Antonine Wall in the 160s AD: inscriptions were buried, altars from the Inveresk Mithraeum were deposited intact, and valued imperial statues were dismantled and hidden rather than destroyed. Dr Fraser Hunter, principal curator of prehistoric and Roman archaeology at NMS, says the statue would have been "a big, impressive monument" of a kind rarely found on the frontier, comparable to the famous Marcus Aurelius equestrian statue in Rome.

Antoninus Pius, the fourth of the "five good emperors" who ruled from AD 138 to 161, never visited Britain. Yet his Scottish campaign was the only foreign war he chose to celebrate with the title Imperator — a battle honour marking a commander's victory. The statue's presence in the Borders would have projected imperial power into a landscape where Iron Age communities had no tradition of naturalistic human representation. The exhibition "Roman Scotland: Life on the Edge of Empire," opening 14 November at NMS in Edinburgh, places the reconstructed leg alongside finds from Inveresk, including a horse burial, painted Mithraic altars with light channels cut into the stone, and a decorated bowl bearing a unique combination of dolphins, stags and a hunting dog.

What remains unknown is the fate of the rest of the statue. No other fragments have been recovered from the Milsington bog, and it is unclear whether the horse, the emperor's torso, or the gilded drapery were melted down, reused, or still lie buried. Hunter calls it a "tantalising glimpse" of the grand monuments that once stood on Rome's northern edge — and a reminder that the frontier was not merely a military line but a stage for imperial theatre.
