Sancho Panza is a character in a poem written by Don Miguel de Cervantes Saavedra.
 It is generally accepted Cervantes died on 22 April 1616 (NS; the Gregorian calendar had superseded the Julian in 1582 in Spain and some other countries); the symptoms described, including intense thirst, correspond to diabetes, then untreatable
Sancho obediently follows his master, despite being sometimes puzzled by Quixote's actions
