- The idea of narrating the adventures of the myth of Perseo was born from a journey in Greece: the hero’s childhood, his encounter with Medusa, his meeting with Atlante and the unintentional killing of his grandfather, Acrisio. This myth, with which the origin of the constellations Andromeda and Cassiopea was explained in the past, is poetic and able to enchant even modern readers.Dossiers on Ancient Greece and the Olympics and a series of comprehension exercises are also included with the text.
