An illustration of a simple five armed crinoid with a detailed view of the tegmen of five orals. Crinoids, also known as sea lilies or feather-stars, are marine animals that make up the class Crinoidea of the echinoderms (phylum Echinodermata). They live both in shallow water and in depths as great as 6,000 meters. Crinoids are characterized by a mouth on the top surface that is surrounded by feeding arms. They have a U-shaped gut, and their anus is located next to the mouth.

A dorsal view of a chiton, showing the eight shell plates. Chitons are small to large, primitive marine mollusks in the class Polyplacophora. There are 900 to 1,000 extant species of chitons in the class, which was formerly known as Amphineura. Chitons have a shell which is composed of eight separate shell plates or valves. These plates overlap somewhat at the front and back edges, and yet the plates articulate well with one another. Because of this, although the plates provide good protection for impacts from above, they nonetheless permit the chiton to flex upward when needed for locomotion over uneven surfaces, and also the animal can slowly curl up into a ball when it is dislodged from the underlying surface. The shell plates are surrounded by a structure known as a girdle.

Kailash Temple, also Kailasanatha Temple or Kylas Temple, is one of the 34 monasteries and temples, extending over more than 2 km, that were dug side by side in the wall of a high basalt cliff in the complex located at Ellora, Maharashtra, India, and represents the epitome of Indian rock-cut architecture. It was carved out of one single rock. The Kailash Temple is notable for its vertical excavation — carvers started at the top of the original rock, and excavated downward, exhuming the temple out of the existing rock. The traditional methods were rigidly followed by the master architect which could not have been achieved by excavating from the front.

The Great Pyramid of Giza, also called Khufu's Pyramid or the Pyramid of Khufu, and Pyramid of Cheops, is the oldest and largest of the three pyramids in the Giza Necropolis bordering what is now Cairo, Egypt, and is the only remaining member of the Seven Wonders of the Ancient World. The Great Pyramid is the only pyramid known to contain both ascending and descending passages. There are three known chambers inside the Great Pyramid. These are arranged centrally, on the vertical axis of the pyramid.

Luxor Temple is a large Ancient Egyptian temple complex located on the east bank of the River Nile in the city today known as Luxor (ancient Thebes) and was founded in 1400 <small>BC</small>. The temple properly begins with the 24 meter (79 ft) high First Pylon, built by Ramesses II. The pylon was decorated with scenes of Ramesses's military triumphs (particularly the Battle of Kadesh). Pylon is the Greek term for a monumental gateway of an Egyptian temple. It consists of two tapering towers, each surmounted by a cornice, joined by a less elevated section which enclosed the entrance between them.

The serious, solemn, and awe-inspiring efect which the general arrangement of the temple produces is maintained by the smaller details, while the slanting form of the outer walls gives the temple an appearance of solidity and isolation. On this account, and especially owing to its simple unbroken lines, the exterior although monotonous and heavy, is still imposing. The chief peculiarity in the construction of these buildings is that they produce the effect of being composed of an agglomeration of separate parts, which resemble on another, but become smaller and smaller towards the rear of the structure.

In the capital the Doric echinus is replaced either by a cyma ornamented with leaves, or, more generally, by an ovolo with a pearl-beading beneath. Instead of the Doric abacus there occurs a cushion-like band in its place, whose ends wound in a spiral shape and coiled with elastic force, when viewed either from in front or behind, formed volutes, which on both sides considerably exceed the diameter of the column, and also surpass the architrave in breadth.

These volutes, or scrolls, when viewed from the side, appear to meet in the middle, and form a wavy line over the echinus. The intervals of the spiral coils are slightly hollowed, in order to bring them into more relief, and in this way the so-called channel is formed, which is continued in the horizontal portion which connects the volutes.

Rectangular block under the soffit of the cornice of the Greek Doric temple, which is studded with guttae. It is supposed to represent the piece of timber through which the wooden pegs were driven in order to hold the rafter in position, and it follows the sloping rake of the roof. In the Roman Doric order the mutule was horizontal, with sometimes a crowning fillet, so that it virtually fulfilled the purpose of the modillion in the Corinthian cornice.

It was built in 161 AD by Herodes Atticus in memory of his wife, Aspasia Annia Regilla. It was originally a steep-sloped amphitheater with a three-story stone front wall and a wooden roof, and was used as a venue for music concerts with a capacity of 5,000.
