Gesture and allusion "mean." Allusion, esp. deep allusion as in Duncan's use of it and before, doesn't seem to be so popular these days. Berryman should have been in the Allen anthology--in fact some of the "Dream Songs" are more innovative in terms of Martians voices and the furniture in the room--than Spicer's books, and definitely more innovative than Olson and Creeley (whose gesture--Creeley's--often seems to be that of a failed, Jr. Berryman.)
