The main subject matter is from four events from the Book of Acts, connected with the institution and growth of the Church. On the left, Peter and John are healing the lame man(Acts iii, 6) and the sending forth of Paul and Barnabas(Acts xiii, 3).
On the right we have the martyrdom of St. Stephen(vii 60), and Paul preaching in Athens(Acts xvii,22) The cartoons are small and square in shape, with architectural designs above and below, the whole linked together by the tree of life.
