Санта-Пуденциана
The sky with stars or clouds was often depicted as decoration of domes, apses, and ceilings of churches. The basilica in Rome of Saint Pudentiana ("Santa Pudenziana"), built in the late 4th century, is an example predating Galla Placidia's building, while later buildings at Ravenna repeated the motif, including the Chapel of Saint Andrew (c"apella Sant'Andrea") in the Archiepiscopal Palace and the 6th century basilica of Saint Apollinaris in "Classe" ("Sant'Apollinare in Classe").
