The Boar. Richard III.; so called from his cognisance.
The wretched, bloody, and usurping boar That spoiled your summer fields and fruitful vines; ... This foul swine ... lies now ... Near to the town of Leicester, as we learn.
Shakespeare: Richard III., v. 3.
The bristled Baptist boar, impure as he [the ape], But whitened with the foam of sanctity, With fat pollutions filled the sacred place, And mountains levelled in his furious race.
Part i. 43-6.
