The polyptych was completed by a predella, now divided between several American museums. Below there was a predella of three "grisaille" (monochrome) compartments illustrating the Theological Virtues (1507. The predella below comprised five narrative paintings. One predella panel is in the Hermitage, St Petersburg. Below the two main pictures are three smaller paintings in the predella. In both cases, the supporting plinth ("predella") often featured supplementary and related paintings. Four small and rather simple "predella" panels survive; there were probably originally seven. The predella, painted by Bartolomeo di Giovanni, is in the same site. Only the predella was preserved, which is lost in the archival store of the cathedral. One possibility is that Villate was responsible for a predella now lost. On the predella is his famous A.E.I.O.U. device. The platform is known as the predella. Their remains are stored in the predella. This is now treated as a predella or shelf below the frame of the copy. The little predella picture is probably the earliest.
