That Richard of Gloucester undergoes some kind of transformation at the conclusion of Shakespeare's Henry VI plays few, if any, critics would dispute. The nature of this metamorphosis, how radical it is, and when it occurs are matters that spark debate. Drawing upon elemental ecocriticism and cognitive theory, in particular the “4E perspective” that sees the mind as embodied, enactive, embedded, and extended, this essay takes a fresh look at Richard's transformation by focusing on the relationship between sovereignty, cognition, and the prodigious flow of water in the first tetralogy. Water can refer to the flood of salty tears that threatens to turn England into a swamp of sorrow, but it can also refer to the rivers, oceans, and rain that ultimately elude the grasp of sovereign control. Far from being merely an external manifestation of an internal, self-enclosed cognitive state, tears merge with the rest of the watery world; indeed, water does not respect boundaries between the subjective and the objective, the interior and the exterior. Water provides an especially challenging test for a cognitive theory approach to reading the first tetralogy: if a 4E perspective grounds the senses in a particular place, the flux and formlessness of water would seem to provide at best a merely transitory orientation, shape, or position in space. By the time we reach Richard III, however, we find that Richard's watery thinking defines a powerful, protean self amid the instability of the struggle for sovereignty.
