The light may be dim but the subject of this sculpture certainly wasn’t. Visitors to the Old Library in Trinity College Dublin tend to be so engaged with the architecture of the space that they don’t notice the plinths holding busts that line either side of the room. The all-male gathering features classical philosophers, distinguished figures associated with the college and also, rightly, a number of famous Irishmen. This is scientist Robert Boyle, discoverer of Boyle’s Law (which explains how pressure is inversely proportional to volume) as represented by the Flemish sculptor Peter Scheemakers. In 1743 he was commissioned by the college authorities to produce the first 14 busts in the library. Nearby can be seen Dean Swift by Louis-François Roubiliac which dates from c.1748/49 and is the finest item in the collection.
