Mattia Preti’s Reward from the Order of St John for Painting the Vault of St John’s, Valletta 1661–1666
In September 1661 Grand Master Rafael Cotoner accepted Mattia Preti’s offer to redecorate the interior of the Order’s conventual church of St John in Valletta, and over the following five years Preti designed and painted the whole barrel vault with the life of the Baptist directly onto the stone. For the scheme the Order gave him two gold chains — one valued at 600 scudi, presented in January 1662, a second worth 300 in June 1663 — together with cash payments of 1,000 scudi in 1662 and a further 1,000 on 20 December 1666. The figure converted here is the 2,000 scudi of cash only; it bundles Preti’s design, his own hand and his assistants’ labour, and his modern biographer observes it could hardly be called payment for so vast a scheme. The scudo was a money of account, so the gold value rests on the Order’s own zecchino standard and on a tariff of forty-three tarì to the zecchino recorded a generation later, which if anything understates it.
