   • 1850, Karl Otfried Müller and John Leitch (translator), Ancient Art and Its Remains; or, A Manual of the Archæology of Art‎, page 146:

     The Etruscans, then, appear in general as an industrious people ( φιλότεχνον ἔθνος), of a bold and lofty spirit of enterprise, which was greatly favoured by their priestly aristocratic constitution. Massive walls, mostly of irregular blocks, surround their cities (not merely their acropoleis); the art of protecting the country from inundations by the construction of canals, and outlets from lakes, was very zealously practised by them.
