Pope Caius (died 22 April 296), Little information on Caius is available except that given by the Liber Pontificalis, which relies on a legendary account of the martyrdom of Susanna of Rome for its information. According to legend, Caius baptized the men and women who had been converted by Tiburtius (who is venerated with Susanna) and Castulus. His legend states that Caius took refuge in the catacombs of Rome and died a martyr.

Pontificate

thumb|Remains of the [[basilica of Salona.]]

Christian tradition makes Caius a native of the Dalmatian city of Salona, the son of a man also named Caius or Gaius, and a member of a noble family related to the Emperor Diocletian. About 280, an early Christian house of worship was established on the site of Santa Susanna, which, like many of the earliest Christian meeting places, was in a house (domus ecclesiae). The domus belonged, according to the sixth-century acta, to brothers named Caius and Gabinus, prominent Christians. Caius may be this pope, or Caius the Presbyter. Gabinus is the name given to the father of Susanna. Thus, sources state that Caius was the uncle of Susanna.

As pope, Caius decreed that before someone could assume the position of bishop, he must first be porter, lector, exorcist, acolyte, subdeacon, deacon, and priest. He also divided the districts of Rome among the deacons. During his pontificate, anti-Christian measures increased, although new churches were built and cemeteries were expanded. Over the course of the next few years, the entire group would be discovered one by one by Roman authorities and martyred. In 1631, his residence in Rome was turned into a church. However, it was demolished in 1880 to make room for the Ministry of War, on the Via XX Settembre, and his relics were transferred to the chapel of the Barberini family.

Saint Caius is portrayed in art wearing the papal tiara with Saint Nereus. He is venerated in Dalmatia and Venice. In Florence, the church of San Gaggio on the via Senese was dedicated to him; the term Gaggio is a corruption of the name Cajo. In 2003, plans were put into effect to turn it into residential council housing.
