The relief decoration of the front side of the chest has been roughed-out with the point chisel. The marks of this stage of work are still visible on the background, which the carver never got around to carving.
Rough shaping with the flat chisel (or perhaps a slightly round-headed chisel on the right) can be seen on the leg of the putto and the drapery on the right.
The column at the centre of this scene is carved more finely than the rest of the relief. The fact that areas around this are only point chiselled shows that the carver was working into the chest from the front to the back, adding details as they went.
