"But Pallas now Tydides’ soul inspires, Fills with her force, and warms with all her fires, Above the Greeks his deathless fame to raise, And crown her hero with distinguish’d praise. High on his helm celestial lightnings play, His beamy shield emits a living ray; The unwearied blaze incessant streams supplies, Like the red star that fires the autumnal skies, When fresh he rears his radiant orb to sight, And, bathed in ocean, shoots a keener light."

"Great Hector, cover’d with his spacious shield, Plies all the troops, and orders all the field. As the red star now shows his sanguine fires Through the dark clouds, and now in night retires, Thus through the ranks appear’d the godlike man, Plunged in the rear, or blazing in the van; While streamy sparkles, restless as he flies, Flash from his arms, as lightning from the skies."

"Him, as he blazing shot across the field, The careful eyes of Priam first beheld. Not half so dreadful rises to the sight, Through the thick gloom of some tempestuous night, Orion’s dog (the year when autumn weighs), And o’er the feebler stars exerts his rays; Terrific glory! for his burning breath Taints the red air with fevers, plagues, and death. So flamed his fiery mail."

"Still from the living root the mantling green Against the Dog-star spreads a leafy screen."
