Il vomere: bozzetto per vetrata del Ministero dell’Agricoltura, Industria e Commercio

This room takes its name from the large piece of stained glass in the form of a nail, made by Duilio Cambellotti and elaborately decorated with vine leaves and bunches of grapes.
The motif is repeated in the delicate monochrome work in stucco which emphasises the panels of the ceiling and in the tondo at its centre, from which a chandelier of wrought iron originally hung.

The room was used as a studio by the Prince, but its furniture has been lost.
