She helped the poor and infirm and founded the first nunnery in Europe at Poitiers in western France.
Created between 1496-98, the French manuscript shown here was made for Charles VIII of France and his consort Queen Anne of Brittany.
It was illuminated by the Poitevin miniaturist dubbed ‘the Master of St Radegund’ and features representations of the monarchs themselves in the illustrations.
It is one of 18 works unveiled by The European Fine Art Foundation (TEFAF) ahead of the second iteration of TEFAF Online, which runs from September 9-13 with an invitation-only preview on September 8.
The manuscript is among more than 700 works of art to be displayed digitally at the fair and is offered by Basel dealer Jörn Günther priced at €880,000.
