Extract

In about 1380 the choir of the Franciscan church of Florence, Santa Croce, was decorated by Agnolo Gaddi with scenes illustrating the legend of the Holy Cross. The emperor Constantine does not appear in these frescoes, although it was understood that it was his conversion that had moved his mother Helena to undertake her archaeological expedition to the Holy Land to discover the whereabouts of the Cross. It is, nevertheless, his unseen presence that links Gaddi’s cycle to the frescoes of the life and miracles of Saint Silvester, painted by Maso di Banco in the nearby Bardi di Vernio chapel a generation earlier. Here the emperor, afflicted with leprosy, recoils from the advice of his pagan priests that he should bathe in the blood of innocent children and is advised by the apostles Peter and Paul in a dream that to obtain a remedy he must send for the persecuted pope Silvester. Silvester shows Constantine portraits of the apostles, thus authenticating his vision, and cleanses him of his leprosy by baptism. The remaining frescoes illustrate miracles of the saint, notably his quelling of a dragon that had been terrorising Rome and his resuscitation of two magicians who had been overcome by it.

This would presume that Valla’s demonstration was immediately accepted as conclusive; but Podro also suggests more strictly artistic and liturgical reasons for Constantine’s appearance at Arezzo.

18 Legenda, pp 306-7: ‘Certum est autem, quod sub Silvestro papa christianus effectus est, utrum autem baptismum distulit in dubium vertitur, unde de illa legenda sancti Silvestri quo ad plura sirmliter dubitatur. Haec igitur hystoria de inventione sanctae crucis, quae in ecclesiasticis hystoriis invenitur, cui edam consonant chronicae, videtur esse magis authentica quam illa, quae per ecclesias recitatur. Constat enim multa ibidem esse, quae non consonant ventati, nisi forte quis vellet dicere, ut seapius dictum est, quod non fuit Constantinus, sed Constantinus pater ejus; quod tamen multum authenticum non videtur, licet in quibusdam ultramarinis hystoriis sic legatur’. I have as yet been unable to identify exactly what the ultramarinae hysloriae referred to by Jacopo were. His Syrian Christian contemporary, Gregory Barhebreus (1226-1286) however attributes leprosy and baptism to Constantine’s father and the vision and victory to Constantine himself (The Chronography of Gregory abu’l Faraj, commonly known as Bar Hebreus, ed and trans Wallis-Budge, E., 2 vols (London 1932), 1 p 58 Google Scholar.
