[San Caio](_blank)
at Santi e Beati 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

During his pontificate,
anti-Christian measures increased, although new churches were built and cemeteries were expanded.
Martyrdom
Pope Caius would go into hiding due to increased persecution of the church, alongside Saints Polycarp,
Sebastian,
Tranquillinus,
Tiburtius, Nicostratus and
Zoe, in the house of
Castulus, a Christian officer employed at the Imperial Palace.
Over the course of the next few years, the entire group would be discovered one by one by Roman authorities and martyred.
Caius would be found praying with Tiburtius shortly after the conversion and baptism of Tiburtius' children and the pair was brought to the local

into it to appease the Roman gods, or to cast themselves into it.
Although Pope Caius' ultimate fate is unclear, often being associated with beheading, according to legend Tiburtius walked into the fire invoking the name of Christ and remained unhurt, so he was taken out of Rome by the
Via Labicana and
beheaded.
However, Caius' martyrdom is disputed, as the
Diocletianic Persecution of Christians began in 303 AD, after Caius’ alleged death, and Diocletian was not immediately hostile to Christianity upon becoming emperor.
Legacy
Caius is mentioned in the fourth-century ''
Depositio Episcoporum'' (therefore not as a martyr): ''X kl maii Caii in Callisti''.
Caius' tomb, with the original epitaph, was discovered in the
catacomb of Callixtus and in it the ring with which he used to seal his letters (see Arringhi, Roma subterr., 1. iv. c. xlviii. p. 426).
In 1631, his alleged 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.
