This is a plan of the St Peter's at Rome. It is an example of Italian Renaissance architecture. The construction lasted from 1546 to 1564AD. "In 1505, on the advise of Michelangelo, Bramante was instructed to prepare designs for a new church in Rome dedicated to St Peter, to take the place of the early basilica, which, built in haste, began to show serious signs of failure [...] In 1546 Michelangelo, then seventy–two years of age, was entrusted with the continuance of the work, and he made radical changes, chiefly in the design of the dome.

"Geococcyx californianus. Ground Cuckoo. Chaparral Cock. Road Runner. Snake Killer. Paisano. Most of the feathers of the head and neck bristle-tipped; a naked area around eye; crown crested; plumage course. Above, lustrous bronzy or coppery-green, changing to dark steel-blue on the head and neck, to purplish-violet on the middle tail-feathers; everywhere except on rump conspicuously streaked with white, mixed with tawny on the head, neck, and wings - this white and buff streaking consisting of the edges of the feathers, which are frayed out, fringe-like, producing a peculiar effect. Breast, throat and sides of neck mixed tawny-white and black; other under parts dull soiled whitish. Primaries white, tipped and with oblique white space on outer webs. Lateral tail-feathers steel-blue with green violet reflections, their outer webs fringed part way with white, their tips broadly white. Lower back and rump, where covered by the folded wings, dark colored and unmarked; under surface of wings sooty-brown. Bare space around eye bluish and orange. Bill dark horn-color; feet the same, the larger scales yellowish." Elliot Coues, 1884

"The creations of Alberti form a class apart in Florentine palace architecture, for they do not display the peculiarities of the Florentine style, but rather accommodating the forms of the antique to more modern requirements, they pointed out the road which was followed by the Roman Renaissance style, especially at the commencement of the sixteenth century. As will be seen from (this image,) these buildings are, to a certain extent, free from medièval sympathies, and approach more closely to the classical models."

A traction engine is a self propelled steam engine used to move heavy loads on roads, plough ground or to provide power at a chosen location. This is the steering device for a road locomotive. Traction engines were cumbersome and ill suited to crossing soft or heavy ground so their agricultural use was usually either in the belt, or in the pairs.

An armoured train is a train protected with armour. Usually they are equipped with railroad cars armed with artillery and machine guns. They were mostly used during the late 19th and early 20th century, when they offered an innovative way to quickly move large amounts of firepower into position. Their use was discontinued because modern road vehicles became much more powerful and offered more flexibility, and because armoured trains were too vulnerable to track sabotage as well as attacks from the air.

A road vehicle like this one is a mechanical means of conveyance, a carriage or transport. Vehicles may be propelled or pulled by engines or animals including humans, for instance, a chariot, a stagecoach, a mule-drawn barge, an ox-cart or rickshaw. However, animals on their own, though used as a means of transport, are not called vehicles, but rather beasts of burden or draft animals. This distinction includes humans carrying another human, for example a child or a disabled person.
