Small carvings, for a mainly lay and often female market, became a considerable industry in Paris and some other centres. Types of ivories included small, devotional polyptychs, single figures, especially of the Virgin, mirror-cases, combs, and elaborate caskets with scenes from Romances, used as engagement presents. The very wealthy collected extravagantly elaborate, jewelled and enamelled metalwork, both secular and religious, like the Duc de Berry's Holy Thorn Reliquary, until they ran short of money, when they were melted down again for cash.
