I might disagree with Andrew on the Lethe detail. Pound's allusion is not to the river in Greek mythology, but to the river at the crossing between Purgatory and Paradise in Dante's Divine Comedy. At this point, Dante needs to bathe in the river to forget his sins in order to ascend to paradise. Pound does not bathe in the Lethe. On the contrary, he passes over it and remembers everything. The detail is a symbol of the Pisan Cantos as a whole, which are based on memory. Bearing in mind that the poem was composed in the camp, where Pound had almost no books to refer to, everything he says in the Pisan is derived from his remembered experience with almost no aid at all.
