Caius is mentioned in the fourth-century ''[[Depositio Episcoporum]]'' (therefore not as a martyr): ''X kl maii Caii in Callisti''.<ref name="ce"/>

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.&nbsp;426).<ref name="EB1911">{{EB1911|inline=y|wstitle=Caius|volume=4|page=960}}</ref> In 1631, his alleged residence in Rome was turned into a church. However, it was demolished in 1880 to make room for the [[Italian Minister of Defense|Ministry of War]], on the [[Via XX Settembre (Rome)|Via XX Settembre]], and his relics were transferred to the chapel of the [[Barberini]] family.<ref name="San Caio"/>

Saint Caius's [[feast day]] is celebrated on 22 April, as is that of [[Pope Soter]]. They are celebrated jointly in the [[Tridentine calendar]] and in the successive versions of the [[General Roman Calendar]] until that of 1969, since when they are omitted. Both are mentioned under 22 April in the [[Roman Martyrology]], the official list of recognized saints. The entry for Saint Caius is as follows: "At Rome, in the [[Catacombs of Rome#Catacombs of San Callisto|cemetery of Callistus]] on the [[Via Appia]], the burial of Saint Caius, Pope, who, fleeing from the persecution of [[Diocletian]], died as a confessor of the faith."<ref>Martyrologium Romanum (Libreria Editrice Vaticana 2001 {{ISBN|88-209-7210-7}})</ref>

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, Florence|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.<ref>[http://www.comune.firenze.it/firenzelacittanuova/us/n/ac_opere_all_e.htm Firenze la città nuova&nbsp;– Gallery] {{webarchive|url=https://web.archive.org/web/20070324074841/http://www.comune.firenze.it/firenzelacittanuova/us/n/ac_opere_all_e.htm |date=24 March 2007 }}</ref>
