In 1737, Nicolas Chédeville made a secret agreement with Jean-Noël Marchand to publish a collection of his own compositions as Antonio Vivaldi's op. 13, entitled Il pastor fido. Chédeville supplied the money and received the profits, all of which was attested to in a notarial act by Marchand in 1749. This may have been an attempt to give his instrument, the musette, the endorsement of a great composer which it lacked.
