On the third (east) wall the narratives run parallel. To the left in the lunette St Stephen is being led to his martyrdom, and to the right we see him being stoned to death. In the lower register Lawrence is first condemned by Emperor Valerian, then in the adjacent scene he is martyred by being roasted on a gridiron. Between these is an auxiliary motif, seen through a small window, showing the conversion of St Hyppolitus, the chief jailer.
