On the pillar between the Chigi and the Mellini Chapel is a Late Neo-Classical monument for the memory of Prince Agostino Chigi (1858-1896) who died in the Battle of Adwa in the First Italo-Ethiopian War. It was designed by Adolfo Apolloni in 1915. The shape of the marble sepulchre follows the curve of the half-column behind. The plate of the inscription is flanked by two allegorical statues, the personifications of Earthly Life and Eternal Life.
