A monument of importance is the large fragment of a marble statue of the saint discovered in 1551 which underwent restoration (the upper part of the body and the head being new), and is now preserved in the Lateran museum; the paschal cycle computed by Hippolytus and a list of his writings are engraved on the sides of the chair on which the figure of Hippolytus is seated; the monument dates from the third century (Kraus, "Realencyklopädie der christlichen Altertumer", 661 sqq.).
The topographies of the graves of the Roman martyrs place the grave of Hippolytus in the cemetery on the Via Tiburtina named after him, mention the basilica erected there, and give some legendary details concerning him. (De Rossi, "Roma sotterranea", I, 178-79); the burial vault of the sainted confessor was unearthed by De Rossi (Bullettino di archeologia cristiana, 1882, 9-76).
Hippolytus was the most important theologian and the most prolific religious writer of the Roman Church in the pre-Constantinian era.

Nothing you posted here shows veneration. Do you have any other, or is this just like your claim of the choice of languages of the inscription on the cross?
