The aromatics, especially the thus, or frankincense, of Arabia, occupy the xiith book of Pliny. Our great poet (Paradise Lost, l. iv.) introduces, in a simile, the spicy odours that are blown by the north- east wind from the Sabaean coast:
— Many a league,
Pleased with the grateful scent, old Ocean smiles. (Plin. Hist. Natur. xii. 42.)
