In solid silver by the Lille goldsmith Robert de Noyelles (1645-1724) according to the bronze model of Pietro Tacca (Italy 17th century)
The back is just as carefully executed.
Solid silver "Corpus Christi" are very rare under Louis XIV and it is even rarer to find some that are punched and therefore datable and attributable to a very specific goldsmith.
