The text is divided in three parts: the first chapter deals with the origin of these huge stone monuments that, according to the Australian archaeologist V. Gordon Childe, were erected by mythical megalithic missionaries, members of some early Aegean tribes, of the eastern Mediterranean. The chapter ends with the discovery of dolmens in Sicily.

The second chapter is about Sicilian dolmens: Monte Bubbonia, Cava dei Servi, Cava Lazzaro, Avola; every dolmen is different from another, but they all exist in a European typology. In Cava dei Servi the author found anthropological remains that confirm the burial purpose of the artefact, while the few earthenware fragments legitimise dating them back to the early Bronze Age. The dolmen of Avola is a natural structure that has been worked on by hand, as certified by the analysis carried out, only for this text, by a geological laboratory.
The third chapter ends with a new hypothesis that would clarify the disappearance of a big Maltese civilization that had lived between 4000 B.C. and 2200 BC: the Tarxien Culture.
   The text, written clearly and in easy language, includes an interesting international bibliography, more than 60 notes as well as the quotation of famous books which can be consulted in the most prestigious university libraries of the world.
