Commentary Inf XIII 127-129

Dante's 'Iacopo,' who had made himself a 'tangle' (groppo -- [Inf XIII 123]) with the 'bush' (cespuglio -- [Inf XIII 123]) that is, as we shall discover, a nameless Florentine suicide, finds himself at the not very tender mercies of the nere cagne ([Inf XIII 125]) that punish the wastrels who populate the forest of the suicides. Jacomo suffers the reward for his self-destructive largess, while Lano escapes, only to be caught, as we must assume, later.
