On balance far more is known of trade in luxury goods during the twelfth and thirteenth centuries than of trade in essential foodstuffs and minerals such as wheat and salt. This is surprising in a way, because the sources that refer to commodity movements, such as commercial treaties, are often far more eloquent on vital topics such as grain than they are on the myriad luxury items that passed through Acre, Messina and other great ports of the late twelfth century. Partly this emphasis on high-class goods has been the responsibility of recent historians, who saw in the spasms of Mediterranean trade the key to European economic development; partly it is the fault of the treaties and privileges that survive, for there is no knowing whether, say, two hundred salmae of wheat that a monastery was allowed to export free of tolls represented all its export capacity, part of that capacity, or an amount normally well above that capacity—a purely notional figure.
2. Most of the Genoese treaties have been published by C. Imperiale di Sant'Angelo, in the Codice diplomatico delta Repubblica di Genova, 3 vols. (Rome, 1936–1942)Google Scholar, hereafter CDG.
3. Most notably Henri Pirenne.

6. Corneto and ancient Tarquinii are on separate but neighbouring hills The site of the Etruscan city is commonly supposed to have been evacuated during the ninth or tenth century as a result of Saracen attacks. For a brief history of the site, see Hencken, H., Tarquinia and Etruscan Origins (London, 1968), 17–20Google Scholar.

This volume is cited hereafter as OSM (1190). Of course, merchants were expected to move from named ports into the interior should this prove worthwhile–e.g. to inland wheat estates.
8. The article by Supino, P., ‘Corneto precomunale e comunale’, Bullettino del Istituto storico italiano per il Medio Evo, lxxix (1968), 114–47Google Scholar, is the only substantial analysis of the political development of Corneto; the articles by Dilcher, G. in Quellen und Forschungen aus italienischen Archiven und Bibliotheken xlii (1963), 1–12Google Scholar, and in Atti e Memorie della Deputazione di Storia Patria per le antiche provincie Modenesi, ser. ix, iii (1963), 432–43Google Scholar, do not discuss the twelfth century at all adequately.

68. Supino, ‘Corneto precomunale e comunale’, 146, Supino states, 143, that the ‘floridezza economica’ of Corneto ‘è innanzitutto il riflesso di questa incipiente autonomia’. This image can reasonably be reversed: the strength of the commune lay in the economic growth of southern Etruria.
