A drawing of a male figure, three-quarter length: turned half to the right with his right arm raised to his mouth; wearing the pelt of an animal; with an indication of a curling trumpet at his mouth. This is a study for the mounted trumpeter facing the viewer in the centre background of S. Gennaro led to Martyrdom, a fresco in the Duomo, Naples.  

For another study of this figure, see RCIN 901251.

In 1631 Domenichino was commissioned to paint a fresco cycle in the Cappella del Tesoro in the Duomo, Naples. The scheme included the painting of the three lunettes: these frescoes represent, on the entrance wall, The Eruption of Vesuvius; on the wall to the right of the entrance, S. Gennaro protects the City of Naples from the Saracens; on the wall to the left of the entrance, S Gennaro led to Martyrdom.                     

The lunette of The Eruption of Vesuvius was the first of the frescoes in the chapel to be completed, details of the scene deriving, according to the biographer Giovanni Pietro Bellori, from Domenichino's observations during the eruption of 1631-2. Payment for this lunette and for the lunette of S. Gennaro led to Martyrdom is recorded on 26 November, 1633. These lunettes were probably designed concurrently. The lunette of S. Gennaro protects the City of Naples from the Saracens was completed by 12th March, 1637.
