Saints Gervasius and Protasius: The Iconography

In Milan, Saints Gervasius and Protasius. The Judge Astasius ordered that Gervase beaten to death with leaded scourges and Protase beated with sticks and beheaded. By divine revelation blessed Ambrose discovered their bodies, flecked with blood and incorrupt as if they had just died that day. During the translation The movement of a saint's body to a place of reverence such as a special chapel of their bodies a blind man gained his sight by touching the bier and many were set free who had been possessed by demons. – Roman Martyrology for June 19

Gervasius and Protasius were among the earliest martyrs in Milan (Butler, II, 583f). In 386, about two centuries after their death, St. Ambrose wrote to his sister that he had had "a sudden flash of a premonition" (statim subiit veluti eiusdam ardor praesagii) during Mass and suddenly knew where the bodies of the two martyrs had been buried. His priests dug in the indicated spot, and the bodies were discovered and used to consecrate a new basilica, where it is said that they remain to this day. Contemporaries who were there at the time referred to Ambrose's premonition as a "vision" revealed to him by God or perhaps by the martyrs themselves.1

Centuries afterward, a letter falsely attributed to Ambrose filled in the details we see in the image above. In it Ambrose has a vision one night of two youths wearing short boots and dressed in white pallia and colobia (mantles and sleeved garments). They appear again the second night, and on the third St. Paul appears and tells Ambrose where to dig for their relics. When they are found a note in the grave says they are Gervasius and Protasius, twin sons of the saints Valeria and Vitalis. The letter continues with an account of their martyrdom at the order of Count Astacius, who had been told he needed them to sacrifice to the gods if he wanted victory in battle. The youths refused, so one was beaten to death with cudgels and the other beheaded.2 This account is also in the Golden Legend, but it is not clear whether that work was based on the spurious letter or vice-versa.


The iconography of these saints is very unsettled, but a few features are relatively constant.

Usually the twins are portrayed as handsome young men. In the letter attributed to Ambrose he calls them iuvenes ephebos – that is, youths of about 18-20 years old (ibid.). The Golden Legend (ibid.) calls them pulcherrimi iuvenes – "most beautiful" youths. In another instance of the art influencing the hagiography, the adjective may have been influenced by the way the two had already been pictured. In the 6th-century mosaics at right, for example, they are shown as handsome and beardless young men. They are also beardless, if perhaps less handsome, in the 11th-century book cover at right and in most later portraits.

A few images from later times do give them beards. In this one they also have swords and military garb. Neither the genuine letter of Ambrose's nor the spurious one says that they were soldiers, but their father Vitalis was an officer and a nobleman, so the assumption may have been that they had once followed in his footsteps, or simply that the profession of arms was appropriate for men of their age and status. The short boots, characteristic of soldiers, may also have supported such an assumption.

In portraits without the military garb, the saints' attributes are a scourge for Gervasius and a sword for Protasius (example). In one curious case Gervasius holds both a whip and a sword, as if he had been beheaded after the whipping. A statuary group in Milan also seems to assume that both were beheaded, as they have identical swords as their attributes.

Another attribute used occasionally is the hand cross, as in the book cover at right and in this mosaic in Sant'Ambrogio in Milan.

The white tunic and mantle specified in the Legend are perhaps the most common attributes both in portraits and in narrative images, as in the painting at the top of this page and this painting of their arrest.

In the Middle Ages the words colobium and pallium referred to liturgical vestments, which seems to be the reason that Gervasius and Protasius are sometimes dressed as deacons (example).
