Per la verità non sappiamo neppure fin dove il Mediterraneo si estenda: quanto ampi siano i tratti della costa che occupa, fin dove si spinga nelle rientranze del territorio e dove in effetti cessi. Gli antichi greci lo videro da Phasis sul Caucaso fino alle colonne d"Ercole dello stretto di Gibilterra, andando da oriente verso occidente, sottintendendo i suoi naturali confini verso nord e trascurando qualche volta quelli a sud. La saggezza antica insegnava che il Mediterraneo arriva fin dove cresce l'ulivo. 2 immutable, eternal entities. Martin Lewis and Karen Wigen have shown how continents are nothing but cultural creations. 7 The Mediterranean as a "watery continent" is also a cultural invention. "Its boundaries are not defined by space or by time. . . . They are not like those of nation-states: they rather look like a circle traced with chalk which is continuously inscribed and erased; a circle continuously enlarged and shrunk by waves, winds, enterprises, and inspirations." 8 Like Italy, the basin was politically united for the first time only during Roman imperial rule. Before then, the Mediterranean was understood either as an open sea, or an ensemble of seas. In the Old Testament, for example, it was called the "Western Sea," as it lay on the western coast of the Holy Land, 9 the "sea of the Philistines," 10 after the inhabitants of a large portion of its shores near the Israelites, the "Great Sea," 11 or simply "The Sea." 12 Herodotus referred to it with names of smaller seas and gulfs, rather than as a whole. Strabo and other ancient Greeks called it "η εντός και καθ΄ ηµάς λεγόµενη θάλασσα" [the sea over by us], but only in a strictly limited sense. Similarly, the Romans originally envisaged the Mediterranean as a series of smaller seas, whose names most often were taken from neighboring coasts or islands -Mare Tyrrenum, Mare Balearicum, etc. The name Mare Mediterraneum seems not to have been used at all until relatively late. The geographer Solinus appears to have employed it in the second half of the third century A.D. "When the Romans wanted to talk about the whole sea, they referred to it as Mare Magnum, Mare Internum, or Mare Nostrum . . . With control of all the lands around the sea in Roman hands, the Mediterranean became an internal lake, 'our sea.' This complete political dominance and use, of the whole Mediterranean by one single power had never occurred before, nor has it happened again -in quite the same way." 13 Hence, the unity of the Mediterranean as a metageographical object radiated from the heart of the Italian Peninsula -itself a metageographical entity.Coastlines are abstractions, just as boundaries are. 14 As metageographical objects, Italy and the Mediterranean make sense, or rather come into being, only through the superimposition of one another and, thus, only "from above." We can only visualize and imagine them on maps -or rather, as maps. Although it is not until quite recently that we have been able to fully "visualize" these two entities "from above," Italy and the Medite...
