Vergil, Georgics, 4.37-41 :

...neque illae/nequiquam in tectis certatim tenuia cera/spiramenta linunt fucoque et floribus oras/explent collectumque haec ipsa ad munera gluten/et visco et Phrygiae servant pice lentius Idae.

: ...nor for them/for naught the roofs' moilingly with thin wax/the spiracles do they line with rouge and dust by flowers' mouths'/expelled, garnered for the office of cement/than bird-lime which holds more still, or than the pitch from Phrygian Ida's pines.
