Note 1403 — PERSIUS.

Cædimus. A metaphor from gladiators, which is continued through the next three lines. "While we are intent on wounding our adversaries, we leave our own weak points unguarded;" i. e., while satirizing others, we are quite forgetful of and blind to our own defects. There is here also a covert allusion to Nero, who, though so open to sarcasm, yet took upon him to satirize others. Cf. ad Juv., iv., 106, "Et tamen improbior satiram scribente cinædo."
