The Vision of St. Camillo
Vita di San Camillo de Lellis, ed. Pantaleone Dolera
The image shows the vision described on page 28 of the book (I, x). While the saint was praying tearfully before the crucifix, he saw its hands reach toward him and heard a voice saying, "O faint of heart, why are you troubled? Carry on with my support, for it is my work, not yours."
