In the early Middle Ages, there were distinct material cultures evident in the different federations and kingdoms within what is now Scotland. Pictish art was the only uniquely Scottish medieval style; it can be seen in the extensive survival of carved stones, particularly in the north and east of the country, which hold a variety of recurring images and patterns. It can also be seen in elaborate metal work that largely survives in buried hoards. Irish-Scots art from the kingdom of Dál Riata suggests that it was one of the places, as a crossroads between cultures, where the Insular style developed.

Insular art is the name given to the common style that developed in Britain and Ireland from the eighth century and which became highly influential in continental Europe and contributed to the development of Romanesque and Gothic styles. It can be seen in elaborate jewellery, often making extensive use of semi-precious stones, in the heavily carved high crosses found particularly in the Highlands and Islands, but distributed across the country and particularly in the highly decorated illustrated manuscripts such as the Book of Kells, which may have been begun, or wholly created at the monastic centre of Iona.

Scotland adopted the Romanesque style relatively late and retained and revived elements of its style after the Gothic style had become dominant from the thirteenth century. Much of the best Scottish artwork of the High and Late Middle Ages was either religious in nature or realised in metal and woodwork, and has not survived the impact of time and the Reformation. However, examples of sculpture are extant as part of church architecture, including evidence of elaborate church interiors. From the thirteenth century there are relatively large numbers of monumental effigies. Native craftsmanship can be seen in a variety of items. Visual illustration can be seen in the illumination of charters and occasional survivals of church paintings. Surviving copies of individual portraits are relatively crude, but more impressive are the works or artists commissioned from the continent, particularly the Netherlands.

Early Middle Ages

Pictish stones

About 250 Pictish stones survive and have been assigned by scholars to three classes.J. N. G. Ritchie and A. Ritchie, Scotland, Archaeology and Early History (Edinburgh: Edinburgh University Press, 2nd edn., 1991), , pp. 161–5. Class I stones are those thought to date to the period up to the seventh century and are the most numerous group. The stones are largely unshaped and include incised symbols of animals such as fish and the Pictish beast, everyday objects such as mirrors, combs and tuning forks and abstract symbols defined by names including V-rod, double disc and Z-rod. They are found between from the Firth of Forth to Shetland. The greatest concentrations are in Sutherland, around modern Inverness and Aberdeen. Good examples include the Dunrobin (Sutherland) and Aberlemno stones (Angus).J. Graham-Campbell and C. E. Batey, Vikings in Scotland: an Archaeological Survey (Edinburgh: Edinburgh University Press, 1998), , pp. 7–8.

Class II stones are carefully shaped slabs dating after the arrival of Christianity in the eighth and ninth centuries, with a cross on one face and a wide range of symbols on the reverse. In smaller numbers than Class I stones, they predominate in southern Pictland, in Perth, Angus and Fife. Good examples include Glamis 2, which contains a finely executed Celtic cross on the main face with two opposing male figures, a centaur, cauldron, deer head and a triple disc symbol and Cossans, Angus, which shows a high-prowed Pictish boat with oarsmen and a figure facing forward in the prow. Class III stones are thought to overlap chronologically with Class II stones. Most are elaborately shaped and incised cross-slabs, some with figurative scenes, but lacking idiomatic Pictish symbols. They are widely distributed but predominate in the southern Pictish areas.

Pictish metalwork Items of metalwork have been found throughout Pictland. The earlier Picts appear to have had a considerable amount of silver available, probably from raiding further south, or the payment of subsidies to keep them from doing so. The very large hoard of late Roman hacksilver found at Traprain Law may have originated in either way. The largest hoard of early Pictish metalwork was found in 1819 at Norrie's Law in Fife, but unfortunately much was dispersed and melted down.S. Youngs, ed., "The Work of Angels", Masterpieces of Celtic Metalwork, 6th–9th centuries AD (London: British Museum Press, 1989), , pp. 26–8. Over ten heavy silver chains, some over long, have been found from this period; the double-linked Whitecleuch Chain is one of only two that have a penannular ring, with symbol decoration including enamel, which shows how these were probably used as "choker" necklaces. The St Ninian's Isle Treasure of 28 silver and silver-gilt objects, contains perhaps the best collection of late Pictish forms, from the Christian period, when Pictish metalwork style, as with stone-carving, gradually merged with Insular, Anglo-Saxon and Viking styles.L. R. Laing, Later Celtic Art in Britain and Ireland (London: Osprey Publishing, 1987), , p. 37.

Irish-Scots art

Thomas Charles-Edwards has suggested that the kingdom of Dál Riata was a cross-roads between the artistic styles of the Picts and those of Ireland, with which the Scots settlers in what is now Argyll kept close contacts. This can be seen in representations found in excavations of the fortress of Dunadd, which combine Pictish and Irish elements.T. M. Charles-Edwards, Early Christian Ireland (Cambridge: Cambridge University Press, 2000), , pp. 331–2. This included extensive evidence for the production of high status jewellery and moulds from the seventh century that indicate the production of pieces similar to the Hunterston brooch, found in Ayrshire, which may have been made in Dál Riata, but with elements that suggest Irish origins. These and other finds, including a trumpet spiral decorated hanging bowl disc and a stamped animal decoration (or pressblech), perhaps from a bucket or drinking horn, indicate the ways in which Dál Riata was one of the locations where the Insular style was developed.A. Lane, "Citadel of the first Scots", British Archaeology, 62, December 2001. Retrieved 2 December 2010. In the eighth and ninth centuries the Pictish elite adopted true penannular brooches with lobed terminals from Ireland. Some older Irish pseudo-penannular brooches were adapted to the Pictish style, for example the Breadalbane Brooch (British Museum). The eighth century Monymusk Reliquary has elements of Pictish and Irish style.S. Youngs, ed., "The Work of Angels", Masterpieces of Celtic Metalwork, 6th–9th centuries AD (London: British Museum Press, 1989), , pp. 109–113.

Early Anglo-Saxon art

Early examples of Anglo-Saxon art are largely metalwork, particularly bracelets, clasps and jewellery, that has survived in pagan burials and in exceptional items such as the intricately carved whalebone Franks Casket, thought to have been produced in Northumbria in the early eighth century, which combines pagan, classical and Christian motifs.C. R. Dodwell, Anglo-Saxon Art: A New Perspective (Manchester: Manchester University Press, 1982), , pp. 2–4. There is only one known pagan burial in Scotland, at Dalmeny Midlothian, which contains a necklace of beads similar to those found in mid-seventh-century southern England. Other isolated finds include a gold object from Dalmeny, shaped like a truncated pyramid, with filigree and garnet, similar to sword harness mounts found at Sutton Hoo. There is also a bun-shaped loom from Yetholm, Roxburghshire and a ring with an Anglian runic inscription. From eastern Scotland there is a seventh-century sword pommel from Culbin Sands, Moray and the Burghead drinking horn mount.L. Laing, The Archaeology of Late Celtic Britain and Ireland C. 400–1200 AD (London: Taylor & Francis, 1975), , p. 28. After Christianisation in the seventh century artistic styles in Northumbria, which then reached to the Firth of Forth, interacted with those in Ireland and what is now Scotland to become part of the common style historians have identified as Insular or Hiberno-Saxon.C. E Karkov, The Art of Anglo-Saxon England (Boydell Press, 2011), , p. 5.

Insular art

Insular art, or Hiberno-Saxon art, is the name given to the common style produced in Scotland, Britain and Anglo-Saxon England from the seventh century, with the combining of Celtic and Anglo-Saxon forms.H. Honour and J. Fleming, A World History of Art (London: Macmillan), , pp. 244–7. Surviving examples of Insular art are found in metalwork, carving, but mainly in illuminated manuscripts. In manuscripts surfaces are highly decorated with intricate patterning, with no attempt to give an impression of depth, volume or recession. The best examples include the Book of Kells, which may have been wholly or partly created in Iona, and the Book of Durrow, which may be from Ireland or Northumbria. Carpet pages are a characteristic feature of Insular manuscripts, although historiated initials (an Insular invention), canon tables and figurative miniatures, especially Evangelist portraits, are also common. The finest era of the style was brought to an end by the disruption to monastic centres and aristocratic life of the Viking raids in the late eighth century.C. R. Dodwell, The Pictorial Arts of the West, 800–1200 (Yale UP, 1993), , pp. 85 and 90.

Christianity discouraged the burial of grave goods so the majority of examples of insular metalwork that survive from the Christian period have been found in archaeological contexts that suggest they were rapidly hidden, lost or abandoned.C. R. Dodwell, Anglo-Saxon Art, a New Perspective (Manchester:Manchester University Press, 1982), , p. 4. There are a few exceptions, notably portable shrines ("cumdachs") for books or relics, several of which have been continuously owned, mostly by churches on the Continent—though the Monymusk Reliquary has always been in Scotland.S. Youngs, ed., "The Work of Angels", Masterpieces of Celtic Metalwork (London: British Museum Press, 1989), , pp. 134–140. The highest quality survivals are either secular jewellery, the largest and most elaborate pieces probably for male wearers, tableware or altarware. The finest church pieces were probably made by secular workshops, often attached to a royal household, though other pieces were made by monastic workshops.S. Youngs, ed., "The Work of Angels", Masterpieces of Celtic Metalwork (London: British Museum Press, 1989), , pp. 15–16. There are a number of large brooches, each of their designs is wholly individual in detail, and the workmanship is varied. Many elements of the designs can be directly related to elements used in manuscripts. Surviving stones used in decoration are semi-precious ones, with amber and rock crystal among the commonest, and some garnets. Coloured glass, enamel and millefiori glass, probably imported, are also used.S. Youngs, ed., "The Work of Angels", Masterpieces of Celtic Metalwork (London: British Museum Press, 1989), , pp. 72–115, and 170–174 and D. M. Wilson, Anglo-Saxon Art: From The Seventh Century to the Norman Conquest (Overlook Press, 1984), pp. 113–114 and 120–130. None of the major insular manuscripts, like the Book of Kells, have preserved their elaborate jewelled metal covers, but documentary evidence indicates that these were as spectacular as the few remaining continental examples.R. G. Calkins, Illuminated Books of the Middle Ages (Ithaca, New York: Cornell University Press 1983), pp. 57–60.
