This short fragment is taken from Ovid, _Met._ viii. 743.
L. 3. _porte un immense ombrage._ I am under the impression that this
happy use of _porter_ has been suggested to Chénier by the term used
in painting of _ombre portée_, defined by Littré (s.v. _porté_), 'ombre
qu'un corps projette sur une surface.' Chénier frequented painters, and
himself painted.
L. 5. _bandeaux_, fillets. See _vittae_ in Rich, _Dict. of Roman and
Greek Antiq._
