Antonio Mingote and José Manuel Sánchez Ron, colleagues at the Spanish Royal Academy, have joined forces, this time in order to study, through the mastery of their drawings and words, 'all that is above our heads', the world that the young and daring Icarus of mythology started to explore. 'All that is above our heads' means, of course, planets, stars, quasars, galaxies and other objects that populate the universe, but The World of Icarus does not limit itself to just this. It also, above all, concerns itself with other citizens of the skies: the birds (not forgetting the study of their place in the long evolutionary chain of terrestrial life) and the machines invented by humans to fly like them (hot air balloons, dirigibles, planes and space rockets).
