"sojourns with the giants of Brobdingnag and the virtuous Houyhnhnms"

   In his popular satirical travelogue Gulliver's Travels (1726), Jonathan Swift's eponymous explorer journeys through various fantasy worlds populated by an assortment of bizarre creatures.  In Part II he discovers the land of Brobdingnag, and lives amongst a race of giants many times his size.  Later he encounters the ‘Houyhnhnm’; a tribe of highly intelligent horses, whose ruthlessly rationalist society is founded on a slave-race resembling primitive humanity.
