However, one important part of the story, which is connected with the rather unusual nickname – Catabarbara, was omitted. Another equally strange name for this place is Cata Barbara Patricia, which directly translated, simply means “by the barbarian patrician”. It relates to the Goth (barbarian) chieftain and Senator Flavius Valilia, who was the owner of the structure in the V century. Based on the text of his will, after his death it came into the hands of the aforementioned pope. He, at the end of his life, decorated the 18 meter long and 14 meter wide aula in the part of the apse with mosaics (according to Liber Pontificalis). None of them remained, but we know them from descriptions and drawings made in the XVII century, meaning before their destruction. They depicted Christ the Teacher, accompanied by six of his disciples. Simplicius also chose the patron for the newly created church – it was for the first time in Rome – St. Andrew. The church also for centuries to come took on the nickname taken from the distinguished, but unnamed Goth funder.

With time the church underwent slow deterioration, that is why not much was left of it, apart from the marvelous antique marble slabs made in the opus sectile technique. The ruins of the church eventually disappeared under other buildings from the time of Benito Mussolini, when Rome went through a veritable construction boom. The archeological works carried out in the thirties of the XX century allowed for the reconstruction of its appearance. Valuable remains, meaning the aforementioned marble slabs from the IV century, are presently kept at the Museo Nazionale Romano – Palazzo Massimo as well as in the Capitoline Museums (Musei Capitolini). They show mythological motifs and genre scenes (Coachman leading a team of horses, Tiger killing a calf).   They are a testimony to the unparalleled talent of the artists of late antiquity.
