Fresco depicting San Lorenzo

The viewer must keep in mind that the interior of the Rotonda was completely covered in frescoes. Among the strips that have survived, one in particular stands out for its beauty, in the area behind the altar. It is an image of St. Lawrence, the deacon who was born in Spain and was martyred during the persecutions of the year 258. According to the tradition he was burnt on a gridiron with blazing wood beneath it.
