The Testaceus Mount  
 in a closer view. On the slopes of the Testaceus, some constructions 
 were finally built with the passing time, among which the  tomb of Rusticelii  (Sepulcrum Rusticeliorum) 
 clung to the slope in the centre of the mound. It was a 30 square feet round monument 
 made of peperino (volcanic tuff used in Roman construction) built about the end of the Republic. 
 It was only in 1687, during excavations, that the spot of the tomb was found again. 
 If we go further up the climbing way along the hill, we reach, completely at the 
 bottom of the picture, with its unobstructed view of the river, 
 the  House of Volusius Saturninus, 
 suffect consul in 3 AD (additional consul nominated by two at a time).
