This bowl is not strictly porcelain but would have been regarded as such in Europe, where fine ceramics were an exotic rarity. It is now the earliest surviving medieval porcelain brought to England soon after its manufacture. William Warham, Archbishop of Canterbury (d.1532) presented the bowl to New College, Oxford, of which he was then Warden.
