Lope de Vega introduces into two sonnets of Rimas humanas y divinas del licenciado Tomé de Burguillos, references to elements of the classical world that have not been well explained in annotated editions of the poems. This paper discusses, on the one hand, a sonnet containing anecdotes about ancient Greek philosophers, notably, Diogenes, Democritus and Pythagoras; and on the other, a sonnet alluding to The Golden Ass of Apuleius, in which is observable Lope's interest in continuing the tradition of the fictitious author.
