LAND AND PEOPLE. The geographical position of Italy conferred upon her special and obvious advantages for taking up and carrying northward and westward the arts of civilization. A scarcity of good harbors was the only drawback amid the blessings of a glorious climate, fertile soil, varied scenery, and rich material resources. From a remote antiquity Dorian colonists had occupied the southern portion and the island of Sicily, enriching them with splendid monuments of Doric art; and Phœnician commerce had brought thither the products of Oriental art and industry. The foundation of Rome in 753 B.C. established the nucleus about which the sundry populations of Italy were to crystallize into the Roman nation, under the dominating influence of the Latin element. Later on, the absorption of the conquered Etruscans added to this composite people a race of builders and engineers, as yet rude and uncouth in their art, but destined to become a powerful factor in developing the new architecture that was to spring from the contact of the practical Romans with the noble art of the Greek centres.
GENERAL CHARACTERISTICS. While the Greeks bequeathed to posterity the most perfect models of form in literary and plastic art, it was reserved for the Romans to work out the applications of these to every-day material life. The Romans were above all things a practical people. Their consummate skill as organizers is manifest in the marvellous administrative institutions of their government, under which they united the most distant and diverse nationalities. Seemingly deficient in culture, they were yet able to recast the forms of Greek architecture in new moulds, and to evolve therefrom a mighty architecture adapted to wholly novel conditions. They brought engineering into the service of architecture, which they fitted to the varied requirements of government, public amusement, private luxury, and the common comfort. They covered the antique world with arches and amphitheatres, with villas, baths, basilicas, and temples, all bearing the unmistakable impress of Rome, though wrought by artists and artisans of divers races. Only an extraordinary genius for organization could have accomplished such results.
The architects of Rome marvellously extended the range of their art, and gave it a flexibility by which it accommodated itself to the widest variety of materials and conditions. They made the arch and vault the basis of their system of design, employing them on a scale previously undreamed of, and in combinations of surpassing richness and majesty. They systematized their methods of construction so that soldiers and barbarians could execute the rough mass of their buildings, and formulated the designing of the decorative details so that artisans of moderate skill could execute them with good effect. They carried the principle of repetition of motives to its utmost limit, and sought to counteract any resulting monotony by the scale and splendor of the design. Above all they developed planning into a fine art, displaying their genius in a wonderful variety of combinations and in an unfailing sense of the demands of constructive propriety, practical convenience, and artistic effect. Where Egyptian or Greek architecture shows one type of plan, the Roman shows a score.
GREEK INFLUENCE. Previous to the closing years of the Republic the Romans had no art but the Etruscan. The few buildings of importance they possessed were of Etruscan design and workmanship, excepting a small number built by Greek hands. It was not until the Empire that Roman architecture took on a truly national form. True Roman architecture is essentially imperial. The change from the primitive Etruscan style to the splendors of the imperial age was due to the conquest of the Greek states. Not only did the Greek campaigns enrich Rome with an unprecedented wealth of artistic spoils; they also brought into Italy hosts of Greek artists, and filled the minds of the campaigners with the ambition to realize in their own dominions the marble colonnades, the temples, theatres, and propylæa of the Greek cities they had pillaged. The Greek orders were adopted, altered, and applied to arcaded designs as well as to peristyles and other open colonnades. The marriage of the column and arch gave birth to a system of forms as characteristic of Roman architecture as the Doric or Ionic colonnade is of the Greek.

THE ROMAN ORDERS. To meet the demands of Roman taste the Etruscan column was retained with its simple entablature; the Doric and Ionic were adopted in a modified form; the Corinthian was developed into a complete and independent order, and the Composite was added to the list. A regular system of proportions for all these five orders was gradually evolved, and the mouldings were profiled with arcs of circles instead of the subtler Greek curves. In the building of many-storied structures the orders were superposed, the more slender over the sturdier, in an orderly and graded succession. The immense extent and number of the Roman buildings, the coarse materials often used, the relative scarcity of highly trained artisans, and above all, the necessity of making a given amount of artistic design serve for the largest possible amount of architecture, combined to direct the designing of detail into uniform channels. Thus in time was established a sort of canon of proportions, which was reduced to rules by Vitruvius, and revived in much more detailed and precise form by Vignola in the sixteenth century.
