My heart may be, indeed, I think it is, full of the warmest instincts, but they have been unwinged from birth so they can't fly to you.

Some, like tortoises, carry the house wherein they were born; others build theirs, as birds do, on the highest branches of trees, to preserve their young from the insult of unwinged creatures, and they even lay their nests in the thickest boughs to hide them from their enemies.

The Virgin sits at the foot of the cross; before her, and half-sustained by her knees, lies the form of the dead Saviour, seen in front; his arms are held up by two angels (unwinged, as is usual with Michael Angelo).
