The Madonna del Velo.—Among the many works of art, which the unsettled state of the Continent has brought into the London market, are a collection formerly the property of the Bracca family of Milan. The gem of the gallery is a remarkably fine and beautifully finished Madonna del Velo by Raffaelle. This attractive picture derives its title from the Virgin being represented as lifting a transparent veil from the face of the sleeping Jesus. She is gazing on the infant with all the devoted love of a mother, and with all a Madonna’s reverence beaming from her eyes and depicted in her countenance and her posture; while the young St. John is standing by, an attentive and interested spectator of the proceeding. The colors are very beautiful, and are blended with the highest taste and judgment. The details of the painting bear the closest examination, and every new inspection brings to view some unobserved charm, some previously undetected beauty. The figures are worthy in all respects of the highest praise, and the landscape forms a delightful and effective back-ground. To mention one little example of the singular skill and finish displayed in this beautiful work, the veil which the Virgin is represented as lifting from the sleeping infant’s face, is marvelously painted. It is perfectly transparent, and seems so singularly fine, filmy and light, that it has all the appearance of what a silken cobweb might be imagined to be. It is a remarkable specimen of the skill of the great artist even in the most difficult and delicate matters. Indeed, the whole painting is a “gem of purest ray.” * * * * *
