Introduction

Crossing the threshold of the Academy of Fine Arts in Bologna, the entrance corridor presents a look that represents the history and artistic tradition of this institution. In fact, the space preserves an important and majestic corpus of sculptural works set up around 1860, in order to give a fascinating and emblematic perspective view. In the initial part of the corridor, in particular, the numerous bas-reliefs set in the walls grouped in geometric shapes are striking. These are plaster casts of the fifteenth-century panels of the three portals of the Basilica of San Petronio in Bologna which were executed between 1810 and 1820. The originals date back to the '300 and' 400 d.C. including the group of the Porta Magna made by Jacopo della Quercia, the well-known Sienese sculptor.

As with all-round sculptures, these casts served also as models for students who practiced drawing, still maintaining this educational function. Recently, they have also been used as a fundamental reference for the restoration of the original panels of the door of the Basilica of Piazza Maggiore.

A plaque on the left wall of the corridor bears witness to the additional decorative value of these panels, placed at the entrance of the Academy to amaze the visitor and show the beauty of art: "Who admires the plaster molds, marveling at the strength and the intelligence of art, preserves the evidence of the existence of the Petroniana Basilica, through the entrance walls instead of through the books".

A curious anecdote is told about these bas-reliefs. Mr. Pietro Onofri, a man working as a janitor at the Academy, collaborated in the cast of three of the panels, taking the nickname of "il Formetta".

The structure and groups of panels

In the two side walls of the corridor, the different sections of the entire doors are clearly visible although placed in random order. Among all the tiles, those made by Jacopo Della Quercia for the Porta Magna, are recognizable by the subjects represented.

The jambs of the portal are composed of ten bas-relief panels depicting the Genesis Stories, of which six are visible in the central line of the left side.

The scenes of the New Testament, placed in the architrave of the Porta Magna, are positioned below the arched panels on the right wall.

The prophets in the middle arc are instead referable to the work of Antonio Minello and Antonio da Ostiglia, except for the Mosé in the center which appears to have been made by Amico Aspertini.

The Genesis Stories

The panels represent some significant episodes of the Genesis Stories, including the Creation of Adam, the Creation of Eve, the original Sin, the Expulsion from the earthly Paradise, the Work of the progenitors, the Sacrifice of Cain and Abel, the Killing of Abel, the Exit from the Ark of Noah, the Awe of Noah and the Sacrifice of Isaac.

The Creation of Eve

In the Paradise, mentioned only with a chipped rock and two saplings in the background, God creates Eve, with a blessing gesture that makes her rise from the rib of sleeping Adam.

The original Sin

The scene represents the moment in which Eve captures the forbidden fruit from the tree on which the tempting Serpent is rolled. Adam assists condescendingly.

The Expulsion from Paradise

The scene is inspired by the vitality of the Expulsion of Masaccio: Jacopo della Quercia copies the pose of eve from Venus Pudica, while further developing the conflict between Adam and the Angel.

The work of the progenitors.

The environmental notations are very scarce, given only by the ground on which Adam works the earth with difficulty, while Eve, with her children Cain and Abel at her feet, is intent on spinning.
