Oil on copper, 29.5cm by 39.5cm.
The artist, who was the son of Giacinto Gimignani (1611-1681), was active mainly in painting altarpieces for churches in Rome.
In 1672, he joined the Accademia di San Luca, a prestigious association of artists in Rome and was named curator of the Gallery of the Palazzo Quirinale by Pope Alexander VII.
‘Romanelli’ is written on the reverse, and a further attribution to Pietro Paolo Baldini (1614-1684) has also been suggested.
