Torrs Pony-cap and Horns
The Torrs Horns and Torrs Pony-cap (once together known as the Torrs Chamfrein) are Iron Age bronze pieces now in the National Museum of Scotland, which were found together, but whose relationship is one of many questions about these "famous and controversial" objects that continue to be debated by scholars. Most scholars agree that horns were added to the pony-cap at a later date, but whether they were originally made for this purpose is unclear; one theory sees them as mounts for drinking-horns, either totally or initially unconnected to the cap. The  three pieces are decorated in a late stage of La Tène style, as Iron Age Celtic art is called by archaeologists. The dates ascribed to the elements vary, but are typically around 200 BC; it is generally agreed that the horns are somewhat later than the cap, and in a rather different style. Whatever the original appearance and functions of the objects, and wherever they were made, they are very finely designed and skillfully executed, and form part of a small surviving group of elaborate metal objects found around the British Isles that were commissioned by the elite of Iron  Age British and Irish society in the final centuries before the arrival of the Romans. Modern history. The artefacts were found together, "about 1820" and "before 1829", in a peat bog at Torrs Loch, Castle Douglas, Kelton, in the historical county of Kirkcudbrightshire , Dumfries and Galloway, Scotland, the context suggesting they were a votive deposit (the bog being the bed of a drained loch). It was thought that the horns were detached from the cap at finding, but a recently unearthed contemporary newspaper report says they were attached. They were given by the local antiquarian and author Joseph Train FSA  Scot. (1779- 1852) to the novelist Sir Walter Scott, and long displayed with the horns attached to the cap at Abbotsford House, which was opened for public visits from 1833, soon after Scott's death. The horns are currently exhibited fixed onto the cap, pointing backwards, but were originally mounted pointing forwards, and have also been displayed detached from the cap. A replica was made and is on display at Abbotsford. Description. The cap is decorated in repoussé with vegetal motifs, trumpet-spirals and bird heads, while the horns have "boldly asymmetric" engraved decoration including a human face and the  single complete one terminates in a modelled bird head; it has been suggested that this represents specifically the head of a northern shoveller duck. This probably originally had coral eyes; the other horn lacks its tip. The cap has holes for the ears of the pony; the angle at which the cap is currently displayed, as in the photo here, is designed to show the decoration clearly, and corresponds to that the cap would have had with the horse bowing its head. The photos on the museum website show the normal angle when worn better, with the edges on the  sides roughly parallel with the ground. The engraved decoration on the horns is described by Lloyd Laing as "very neatly incised and very elaborate; each pattern begins with a circular "yin-yang" element and swells outwards into a central design before tailing off into a delicate fan-shaped tip. A tiny full-face human mask has been incorporated into the central element of the larger horn." The pony-cap is 10.5 inches long, and the complete horn 16.5 inches along its curve, the dimensions meaning that the horse wearing the cap "would have had to be a very small one . The cap has a large piece at its back proper left missing, and three ancient repairs, using small plates, each decorated with patterns; in the photograph here one can be seen between the ear hole and the near horn, another vertical near the front edge of the cap. Artistic context. The horns and cap are part of a small group of elaborately decorated objects that are the main evidence for one of the last phases of Insular" La Tène style in Britain and Ireland, known as "Style IV" in an extension of the scheme originally devised by de Navarro for  Continental works. Other objects include the Battersea and Witham Shields, and an especially closely related work is a bronze shield boss found in the river Thames at Wandsworth in London, to the extent that Piggot designates a "Torrs-Wandsworth style"; all these three objects are in the British Museum. The group includes other objects from Britain and Ireland. In a Scottish context, the cap has been seen as a leading example of a distinctive "Galloway style" of La Tène art, closely related to developments in northern Ireland, a short distance across the Irish Sea. Other scholars see the pieces as  imported products, perhaps from "east-central England". Function. The pony-cap is normally regarded as a Celtic example of a champron or chamfrein, a piece of horse armour of the type familiar from the late Middle Ages, but has also been seen as intended to be worn by a human in ritual contexts. This was also the view of local antiquaries when the object was found; in its first publication in 1841 it was described as "a mummer's head-mask", though thought to be medieval. It would have been held on by leather straps, with a plume rising from  the top of the cap. No other metal champron from ancient times is known, but there appear to be Celtic and classical Greek examples in materials such as boiled leather, including one from Newstead Fort, a Roman outpost in Scotland. Another possibility is that the intended wearer was a wooden cult statue of a horse, which would help explain the small size. The theory that the horns were drinking-horn mounts, never joined to the cap in ancient times, was first proposed by Professors Piggott and Atkinson in 1955, and was widely accepted for about three decades, leading to the  horns being detached from the cap and displayed separately. The single surviving bird's head terminal is comparable to much later early medieval examples from Anglo-Saxon burials (for example from Sutton Hoo and the Taplow burial) as well as Irish and Pictish contexts, which are either known or assumed to have decorated the tips of drinking-horns. However the theory depended on the assumption that the holes and rivets used to attach the horns to the cap were all the work of a 19th-century restorer. Subsequent investigation suggested that this was not in fact the case, and "opinion  has swung back" to support the original reconstruction, and by the late 1960s Piggott and Atkinson preferred "to think of the horns as yoke-terminals" for chariots. The possibility remains that the horns were made for a different function, but later attached to the cap at some time before its deposit. Though no actual comparable finds have been made, some parallels have been suggested in representations of similar caps, including a figure of the mythical horse Pegasus on a coin of Tasciovanus, the largely Romanized chief who ruled the Catuvellauni from Verlamion (St Albans) between about 20 BC and 9  AD, and was the father of Cymbeline. The Pegasus appears to wear a cap from which rise two knobbed horns. The remains of horses found in the graves of the Iron Age Pazyryk culture in Siberia were fitted with masks in the shape of stag heads, complete with antlers (another example) or horns (another example). In July 2015, an Iron Age burial of carefully arranged animal bones that included a horse's skull with a cow's horn on its forehead was unearthed in Dorset, England.
