The Old Roman Symbol (Latin: vetus symbolum romanum), or Old Roman Creed, is an earlier and shorter version of the Apostles' Creed. It was based on the 2nd-century Rule of Faith and the interrogatory declaration of faith for those receiving Baptism (3rd century or earlier), which by the 4th century was everywhere tripartite in structure, following Matthew 28:19 ("baptizing them in the name of the Father and of the Son and of the Holy Spirit"), which is part of the Great Commission.
According to the Oxford Dictionary of the Christian Church, the first text attesting it is a letter to Pope Julius I in 340 or 341, and it has recently been argued that it developed in the context of the Arian controversy. Bettenson and Maunder further comment on this that Marcellus had been exiled from his diocese through Arian influence, thus spending two years at Rome, and finally left his creed with Julius, Bishop of Rome.
Additionally c. 400, Rufinus, a priest of Aquileia, left a Latin version in his Commentarius in Symbolum Apostolorum (P.L. xxi. 335B). He believed this to be the Roman creed as the "rule of faith" written by the Apostles at Jerusalem. About at the same time also Nicetas of Remesiana wrote an Explanatio Symboli (P.L. Lii. 865-874B) based on the Old Roman Symbol, but including also the communion of saints.
Though the name "Apostles' Creed" appears in a letter of Saint Ambrose (c. 390), what is now known as the Apostles' Creed is first quoted in its present form in the early 8th century. It developed from the Old Roman Symbol, and seems to be of Hispano-Gallic origin, being accepted in Rome some time after Charlemagne imposed it throughout his dominions.
The Latin text of Tyrannius Rufinus:
Credo in deum patrem omnipotentem;
et in Christum Iesum filium eius unicum, dominum nostrum,
qui natus est de Spiritu sancto ex Maria virgine,
qui sub Pontio Pilato crucifixus est et sepultus,
tertia die resurrexit a mortuis,
ascendit in caelos,
sedet ad dexteram patris, unde venturus est iudicare vivos et mortuos;
et in Spiritum sanctum,
The Greek text of Marcellus of Ancyra:

The Latin (Rufinus) and the Greek (Marcellus) versions are faithful, literal, verbatim translations of each other. The only outstanding difference is the concluding clause in the Greek text, ? ? ("life everlasting"), which has no equivalent in the Latin text. This clause is present in the Apostles' Creed.
The Latin version of Nicetas of Remesiana also follows quite closely the version of Rufinus (usually verbatim) but also includes the vitam eternam, as Marcellus, and the communionem sanctorum, omitted by the other two.
I believe in God the Father almighty;
and in Christ Jesus His only Son, our Lord,
Who was born of the Holy Spirit and the Virgin Mary,
Who under Pontius Pilate was crucified and buried,
on the third day rose again from the dead,
ascended to heaven,
sits at the right hand of the Father,
whence He will come to judge the living and the dead;
and in the Holy Spirit,
the holy Church,
the remission of sins,
the resurrection of the flesh
(the life everlasting).
