From Ronsard's Franciade, Book IV

ON yonder Guilty Plain, long Seasons hence
Perhaps a thousand Years, Helmets and Shields,
And plated harnois shal be found, sad marks
Of memorable War, with sudden wonder
Appal'd the Villager lab'ring the Glebe
Shal hear his Plow-Share crash on buried Armour,
And throw up bones of Horses slain in Battle.
