AG's father, Louis, was a traditional poet in the Poetry Society mode. I've seen a few things here and there. Is Allen's early work available online? His first teacher was Mark Van Doren, who was very traditional, and I've heard that AG's early Columbia poetry was in the metaphysical style. I guess I can look it up.
