Commentary Par XXIII 3

For the blackness of the night that hides things from view, Tommaseo (DDP Tommaseo.Par.XXIII.1-3) was the first to point to Virgil (Aen. VI.271-272): 'ubi caelum condidit umbra / Iuppiter, et rebus nox abstulit atra colorem' (when Jupiter has buried the sky in shade, and black Night has stolen from the world her hues [tr. H.R. Fairclough]).
