Aedem etiam, quae Saturni aerarium fertur, comites eius condiderunt in honorem Saturni, quem cultorem regionis illius cognoverant extitisse. Iidem et montem Capitolinum Saturnium nominaverunt.
His companions also founded the temple, which is called the treasury of Saturn, in honor of Saturn, whom they knew to have been an inhabitant of this region. The same people also named the Capitoline hill the Saturnian.
