This Bible with Postilla of Hugh of Saint-Cher, originating from Brescia (Italy) and ?Lyon (France) in 1507–1511, is now in the Bodleian Library, Oxford U.K. .
Folio 266r is a Postilla to Psalm 67, decorated with borders with flowers (strawberries, acanthus), a coat of arms and a snail.
The snail seems to be hardly protruding from its sinistral, narrowly coiled shell. Unfortunately, the resolution is not high enough to see enough details.
