What though the gnats incessant wave their wings, Vain their ciforts, and harmless are their stings. Soon as their swarms the adverse bound beset, Checked they retire, nor pass the impervious net." He here, like the commentators, regards the modern gnat-curtain as precisely identical with the amphiblcstron of Herodotus, without giving himself the trouble to ])oint out how his epithets 'close' and 'impervious' could be applicable to a casting-net. * aS)tA.ij; iiicertus, et to'^ds lucus.
