As evidenced by the famed Book of Kells and monumental high crosses, Scotland and Ireland have long shared a distinctive artistic tradition. The story of how this tradition developed and flourished for another millennium through survival, adaptation and revival is less well known. Some works were preserved and repaired as relics, objects of devotion believed to hold magical powers. Respect for the past saw the creation of new artefacts through the assemblage of older parts, or the creation of fakes and facsimiles. Meanings and values attached to these objects, and to places with strong early Christian associations, changed over time but their ‘Celtic’ and/or ‘Gaelic’ character has remained to the forefront of Scottish and Irish national expression. Exploring themes of authenticity, imitation, heritage, conservation and nationalism, these interdisciplinary essays draw attention to a variety of understudied artworks and illustrate the enduring link that exists between Scottish and Irish cultures.
