A very beautiful olive-leaf-and-berry moulding occurs frequently; there are also a cable pattern, an elaborate fig-leaf design from a door-jamb, and a deeply fluted column, all built up into the walls of the crypt.
Two Roman inscriptions occur: one is on a stone used as a flat roof-slab, and the other has had a semi-circle cut out of it to form the head of a door-way.
The flat roof-slab contained the names of Severus and his two sons, but the name of Geta has been erased as usual, by order of the brother who murdered him.
The most interesting Roman stone at Hexham is a tombstone with a vigorous carving of a Roman soldier on horseback, carrying the standard, and treading on his prostrate enemy.
The inscription reads:
"To the gods, the shades. Flavinus, a soldier of the cavalry regiment of Petriana, standard-bearer of the troop of Candidus, being twenty-five years of age, and having served seven years in the army, is here laid."
Then there is an altar dedicated to Apollo Maponus by Terentius Firmus, a native of Siena, and prefect of the camps of the Sixth Legion.
Dr. Bruce was of opinion that the Roman stones in the Abbey were brought from Corstopitum—more especially because, in the bed of the river near Hexham, Roman stones abandoned in transit have been found.
This view has been fully confirmed in recent years.
