The promise of the new development in English miniature painting, however, was not to be fulfilled. In the first quarter of the 15th century, examples of great merit were produced, but at a standstill in drawing and fettered by medieval convention. The native art practically came to a close about the middle of the century, just when the better appreciation of nature was breaking down the old conventional representation of landscape in European art, and was transforming the miniature into the modern picture. Whatever miniature painting was to be produced in England after that time was to be the work of foreign artists or of artists imitating a foreign style. The condition of the country during the Wars of the Roses sufficiently accounts for the abandonment of art. Thus the history of the miniature in the 15th century must be sought in the manuscripts of the Continental schools.
