The Dove of the Holy Spirit - St Peter's basilica - Vatican

Stained-glass window with The Dove of the Holy Spirit upon the Monument Cathedra Petri (Altar of the Chair of St. Peter) by Gian Lorenzo Bernini (1666)
(La colombe de l'Esprit Saint au-dessus du trône de Saint Pierre dans l'abside de la basilique Saint-Pierre.)
The whole composition is crowned by the fantastic gilt and stucco Gloria peopled by a host of angels among rays of light and gigantic billowing clouds. In their midst is the precious window of Bohemian glass, divided into twelve sections as a tribute to the Twelve Apostles; a brilliant dove stands out against it, the symbol of the Holy Spirit, the soul of the Church which he never ceases to help and to guide.
