Epigram 27: Doctor Donzago one of wondrous learning

Doctor Donzago one of wondrous learning,
And in Astronomy exceeding cunning:
Of things thats past and comming, hees discerning,
His minde on Prophesies is euer running,
Of Commets, Meteors, Apparitions,
Of Prodigies, and exhalations,
Of Planets, natures, and conditions,
And of the spheares great calculations,
Yet want of one skill, all his cunning smothers,
Who lies most with his wife himselfe or others?
