In one of the first known accounts of Bosch's paintings, in 1560 the Spaniard Felipe de Guevara wrote that Bosch was regarded merely as "the inventor of monsters and chimeras".
Ühes teadaolevalt esimestest Boschi maalide kirjelduses kirjutab hispaanlane Felipe de Guevara 1560. aastal, et Boschi peeti kõigest "koletiste ja kimääride leiutajaks".
