Women artists seem to be all the rage these days. And rightly so. The wealth of exhibitions and publications, the changing role of art galleries and museums, the expanding interests of private collectors, and the resulting attention of the action houses not only prove that there is a thirst for more knowledge but also that art history is a rather dynamic discipline.

Until fairly recently, Portrait of Prince Alessandro Farnese was not one of the paintings I would have made a beeline for when calling in the National Gallery of Ireland. And yet it was the one I went looking for when the gallery finally re-opened its doors to visitors.
