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.
