 One of the largest groups of surviving works of art are the seal matrices that appear to have entered Scottish usage with feudalism in the reign of David I , beginning at the royal court and among his Anglo @-@ Norman vassals and then by about 1250 they began to spread to the Gaelicised areas of the country . They would be made compulsory for barons of the king in a statute of 1401 and seal matrices show very high standards of skill and artistry . Examples of items that were probably the work of continental artists include the delicate hanging lamp in St. John 's Kirk in Perth , the vestments and hangings in Holyrood and the Medieval maces of the Universities of St Andrews and Glasgow .
