Carolingian miniatures - Medieval art

The left miniature is from the gospel of Ebbo: Saint Mathew(before 823 A.D.) The right miniature is from the Four gospels (845-882 A.D.) I encountered these online at http://www.hp.uab.edu/image_archive/cr-03/index.html

I find it is very interesting to compare how the art has evolved during Medieval period using these two images. The left image is very dramatic, even theatrical I should say. All the lines sketched on the dress and background, his hair... shows as if the wind blows so hard that St. Mathew is just seconds from being blown away from his chair. His face expression shows a bit of fear, and also deep concentration, look how big his eyes are.. His fingers are portrayed in such awkwardness, but keep the same fluent movement of waves, probably from the strong wind. Even from looking at the frame alone, the waves on the frame created a feeling as if the wind blows out of the picture.. On both, there is a small angel flying on the upper right corner. Only on the left, the angel is less detailed, but I assume that here, the religious experience is so powerful and well presented that there is no need in so much detail.

On the right picture, I am not sure about who this figure represent, but the individual is sited at the same position, only he seem to be reading instead of writing. Here, the scene is less dramatic, bit I think it is also powerful because now, instead of using lines or sketches, the artist is using the power of the light, or Ora, that surrounds the figure to show its religious greatness. But itself, I found the background to be more calm, more detailed.

What do you think??
