The magnificent bronze doors of Hildesheim Cathedral, the ivory, gold, enamelled and bejewelled book covers made to contain superbly illuminated manuscripts, the startling reliquary caskets made in the shape of the part of the body supposed to be contained within them — these and other sacred objects were contained within church treasuries and cloisters in the early Middle Ages in Europe. This book traces the development of these so-called Minor Arts and the major role they played alongside the other pictorial arts and architectural sculpture of the period.
