The author hears a hoarse voice calling him from the bottom of an extinct volcano. That sound, similar to a lament, reminds him that there is a crack that tears Italy from Sicily to Friuli: that of earthquakes. Rumiz decides to follow it, to enter “with Aladdin’s lamp” into the world of the Minotaur. A journey into the foundations of the country, into a hell of fault lines, craters, underground rivers, mines, catacombs and seabeds; into a world without stars that ignites the most intimate vibrations of Italians, a Terra Incognita that takes us straight into the underworld of the Human and opens dizzying itineraries within ourselves. The result is a story marked “by piratesque raids, litanies, spells, landslides, abandonment and corruption; an epic of shipwrecks, invasions, unheard-of capacities for rebirth and fears of the end of the world”. An immense fresco, where the Terrible of nature is a normality against which to equip ourselves and not an emergency on which to speculate; a visionary story that, from Selinunte to the sanctuary of Oropa in the Alps, encounters the shadow of Great Mothers, sibyls and madonnas, and has as its center Naples, the most underground, unstable, stratified, magmatic and at the same time most theatrical metropolis in Europe. It is there that Rumiz, listening to scientists, poets, musicians, anthropologists and inhabitants of those places, deepens his "geological" approach to national identity.
