The transom has never been found. The current stone is the work of the mason commissioned by Duncan to
reconstruct the cross in 1823. The carvings are masonic symbols and were supplied by Duncan, a keen
freemason. On the south side there is a triangle at the centre, flanked by a whale or dolphin to the left
and a dragon to the right. On the North side there is a sunburst at the centre, flanked by a rooster
to the left and a calf to the right. It is clear that the evangelists Mark and Luke would have appeared
with their symbols in the arms of the transom, but what would have been depicted in the centre is a
matter of debate.
