Fionnuala Croke selects a painting attributed to Juan Do from the collection at the National Gallery of Ireland.

It is always intriguing when a painting of high quality cannot with absolute certainty be ascribed to a well-documented artist, as is the case with Christ Disputing with the Doctors (Fig 1) which was acquired by the National Gallery of Ireland in 2001 and features in the Gallery’s current exhibition Taking Stock – Acquisitions 2000–2010.
