in this difficult work. Clement Birago, also a Milanese, cut on the
diamond the likeness and coat of arms of Prince Charles, son of Philip
II. ; and this is asserted by Clusio, Lomazzo, and Giulianelli. It is
said that the celebrated Caradosso delighted in similar work. A lion's
head, a Leda, and a head of Antinous, were, according to Caire,
engraved in diamond by Giovanni and Carlo Costanzi, who were Romans.
Whilst
Venice, London and Amsterdam with treaties of commerce provided for the
necessity of procuring sets of rough diamonds, France, after Colbert,
did not foresee that the diamond mines of India would be nearly
exhausted ; and meanwhile fettered the art of diamond-cutting, by
making regulations even to the number of tools to be retained by each,

although, under the great minister of Louis XIV., there had been
seventy-five engravers, the greater part of them were dispersed at the
revocation of the Edict of is antes : some withdrew to Holland, others
to England, and the few who remained lost their work for want of the
rough material.
