Tractate of Petrarch called «Remedies for fortune fair and foul» consists of seven dialogues dedicated to the topic of friendship.

As the analysis of the text shows this topic is due to Petrarch’s reading of classical authors. The revelations of Italian humanist concerning friendly relationships among men are openly paralleled the ideas of Aristotle, Cicero and Seneca; and also are illustrated by citations from Roman poets.

Close analysis of the dialogues’ style allows the author to come to the conclusion that numerous stylistic formula elaborated in classical antiquity are widely used in Petrarch’s own style.
