Evidence Giuliana Montanari gathered from the Medici records supports this conclusion. While Cristofori's spinettoni were constantly loaned out from the Medici collection for use, this is not so for the oval spinets, which according to Montanari "remained in the same places, gradually deteriorating." Given that the oval spinet failed to achieve popularity at the Medici court, it is unlikely it would have been adopted in society at large, given the expense of building it and the conservatism of the instrument-makers' guilds of the time.
