wherever more accurate specifications were required, they accustomed themselves to reckon by terms of ten months of a solar year of 365 days or by the so-called ten-month year of 304 days. Over and above this, there came early into use in Italy, especially for agricultural purposes, the farmers' calendar based on the Egyptian solar year of 365 1/4 days by Eudoxus (who flourished 386). Structural and Plastic Art A higher idea of what the Italians were able to do in these departments is furnished by their works of structural and plastic art, which are closely associated with the mechanical sciences. Here too we do not find phenomena of real originality; but if the impress of borrowing, which the plastic art of Italy bears throughout, diminishes its artistic interest, there gathers around it a historical interest all the more lively, because on the one hand it preserves the most remarkable evidences of an international intercourse of which other traces have disappeared, and on the other hand, amidst the well-nigh total loss of the history of the non-Roman Italians, art is almost the sole surviving index of the living activity which the different peoples of the peninsula displayed. No novelty is to be reported in this period; but what we have already shown(31) may be illustrated in this period with greater precision and on a broader basis, namely, that the stimulus derived from Greece powerfully affected the Etruscans and Italians on different sides, and called forth among the former a richer and more luxurious, among the latter--where it had any influence at all--a more intelligent and more genuine, art. Architecture-- Etruscan We have already shown how wholly the architecture of all the Italian lands was, even in its earliest period, pervaded by Hellenic elements. Its city walls, its aqueducts, its tombs with pyramidal roofs, and its Tuscanic temple, are not at all, or not materially, different from the oldest Hellenic structures. No trace has been preserved of any advance in architecture among the Etruscans during this period; we find among them neither any really new reception, nor any original creation, unless we ought to reckon as such the magnificent tombs, e. g. the so-called tomb of Porsena at Chiusi described by Varro, which vividly recalls the strange and meaningless grandeur of the Egyptian pyramids.
