While, between the Annunciation and incidents occurring during the infancy of Christ, many years must be presumed to have passed, from this latter period on, the Madonna must be supposed to have aged very little, if at all, right up to the Crucifixion. It is not often that we find her included in a design illustrating the life of Christ between His infancy and the Death Scene, a fact probably due to the age difficulty. In the exceptions her face is often partly or wholly hidden. But in scenes of the Crucifixion, where the Virgin is almost invariably introduced, artists of all periods, with few exceptions, have been careful to avoid suggesting the full presumed age. Commonly the age indicated is between twenty-five and thirty years, but as the face is always pale, and often somewhat drawn, her comparatively youthful appearance is not conspicuous. Obviously under no circumstances should lines be present in the features, for this would suggest a physical decay not in conformity with Christian ideas.[40] Even in pictures relating to her death, which is presumed to have occurred at an age between fifty and sixty years, her face is shown with perfectly regular and smooth features, though an extreme pallor may be painted. But from the point of view of art, the Virgin must be regarded as an accessory in works relating to the Crucifixion, for to throw her into prominence would result in dividing the attention of the observer of the picture on first inspection, and so lessening the art. In any case she must be painted with an expression of grief, and hence an unalloyed ideal of transcendent beauty is out of the question.
