Commentary Inf IV 123
For Caesar as the first emperor see Conv.IV.v.12. For the Suetonian source of his falcon-like eyes see DDP Campi.Inf.IV.123. That Caesar is here in armor may well be a reminder of his crossing of the Rubicon in arms to attack Rome (see Stul.1991.1, p. 36). (Pertile wonders at the reasons for Caesar's being in arms -- Pert.1980.1, p. 17.)
