There
are only three hearts, as far as I know, which are regularly depicted in the
Catholic artistic tradition – the Most Sacred Heart of Jesus, the Immaculate
Heart of Mary, and the heart of St. Thomas Aquinas. Now let me be clear, I am
not claiming that the sunburst so often depicted on St. Thomas’ breast is
literally his heart – neither, of course, are the images of Christ’s or Mary’s
Hearts depictions of physical organs – but it is quite striking that the
sunburst is over the Common Doctor’s heart (and not, for example, upon his
brow).
I
do not in any sense intend to equate St. Thomas’ sunburst with the Hearts of
Jesus and Mary, but it will be good for us to consider the simple fact: No
other saint’s heart is regularly depicted in Christian art. There are,
certainly, many saints whose hearts might have been given this focus – consider
St. Philip Neri, whose heart was physically enlarged with Love; or St. Charles
Borromeo, whose heart is preserved incorrupt; or perhaps even St. Edmund
Campion, whose heart was torn from his body. However, there is no other saint
whom the Christian artistic tradition regularly depicts with a special focus on
their heart.
What
is it about St. Thomas Aquinas that gained him the image of the sunburst, and
why is it placed over his heart?
