Folding Harpsichord, Rijk van Arkel, 1768
In Paris, 1699, Jean Marius (?–1720) claimed credit for inventing the folding harpsichord. Such instruments were convenient when travelling. The right-hand part hinges round to meet the middle part; these two then fold round over the long, left-hand part. The famous castrato Farinelli (1705–1782) owned two such harpsichords, as well as five normal ones and his beloved grand piano.
