De Verborum Significatu
Sextus Pompeius Festus
Mutini Titini sacellum fuit in Veliis, adversum murum Mustellinum in andirtu>, de quo aris sublatis balnearia sunt
The shrine of Mutinus Titinus (also known as Mutunus Tutunus) was on the Velia, opposite the Mustellinum wall, in an alley; when the altars had been removed from it, the baths of the house of Cn. Domitius Calvinus were built, although it (the shrine) had existed from the founding of the city up to the principate of Augustus.
