The Aeneid

The good Aeneas, paternal care Iulus' absence could no longer bear, Dispatch'd Achates to the ships in haste, To give a glad relation of the past, And, fraught with precious gifts, to bring the boy, Snatch'd from the ruins of unhappy Troy: A robe of tissue, stiff with golden wire; An upper vest, once Helen's rich attire, From Argos by the fam'd adultress brought, With golden flow'rs and winding foliage wrought, Her mother Leda's present, when she came To ruin Troy and set the world on flame; The scepter Priam's eldest daughter bore, Her orient necklace, and the crown she wore Of double texture, glorious to behold, One order set with gems, and one with gold.†

foliage = plant leaves

All on the Trojan gifts with wonder gaze, But view the beauteous boy with more amaze, His rosy-color'd cheeks, his radiant eyes, His motions, voice, and shape, and all the god's disguise; Nor pass unprais'd the vest and veil divine, Which wand'ring foliage and rich flow'rs entwine.†
