Here, collected from different websites, are images of David's medallion portraits depicting the former Montagnard deputies who were imprisoned with him in the Collège des Quatre-Nations after the insurrection of Prairial (28th May 1795.)
According to Louis-Antoine Prat there are now nine known portraits, five in public galleries, four in private collections. Clearly they are intended as part of a series: they are uniform in format: circular, of similar size (c.18-19 cm) and executed in pen and ink with wash.
At one level these are very immediate works. In his first period of imprisonment David had felt himself isolated but this time he was thrown together with his companions. At Quatre-Nations the deputies were segregated from other prisoner and detained in makeshift cells around the third, innermost courtyard of the building. They shared a kitchen, and were allowed to gather and talk in the courtyard, also to receive visitors. Much of their time was spent in writing personal defences for publication. The inscription on the portrait of Jeanbon Saint-André notes that it was "a gift of friendship", drawn "in chains", implying that David sketched it there and then in prison .The Jeanbon Saint-André, the Bernard de Saintes, and the "Zurich" portrait have exact dates, 8th 24th and 16th July respectively (David was released on 3rd August). Other portraits have have a background of bricks which suggest a prison wall.
