The corners, nails, locks and hinges of the wooden case which had got in contact with the bones of the Saint were regarded as precious “contact
relics” and were therefore kept in the former grave which was no longer in use.
The fragment of the marble architrave may be a part of a small architectural complex, maybe a ciborium (a canopy over the altar) which
was built over something important. It dates from the second half of Sth century and 9th century and was probably made to recall the presence and the burial of the Saint. Giovanni Mennella proposes the following interpretation:
(—extru)cta ob diem (?) (—)
which may be a reference to the building commemorated by the dedication on the architrave.
