Bassae is an archaeological site in Oichalia, the northeastern part of Messenia, Greece. In classical antiquity, it was part of Arcadia. It is famous for the well-preserved mid- to late-5th century BC Temple of Apollo Epicurius.
Although this temple is geographically remote from major polities of ancient Greece, it is one of the most studied ancient Greek temples because of its multitude of unusual features. Bassae was the first Greek site to be inscribed on the World Heritage List, in 1986.
The temple of Apollo Epikourios construction is placed between 450 BC and 400 BC; the plague its dedication related to was probably the plague of Athens of 430 BC. It was in use until the 4th- or 5th-century AD, when all pagan temples were forcibly closed during the persecution of pagans in the late Roman Empire. Probably because of the remoteness of the site, the temple remained unusually well-preserved. Depictions by artists, which begin in the early 19th century, show the pteron or external colonnade standing complete, and the architrave nearly so. The internal walls were a mass of fallen blocks, but relatively few had been removed for reuse, the normal fate of these conveniently sized pieces.
The temple is unusual in that it has examples of all three of the classical orders used in ancient Greek architecture: Doric, Ionic, and Corinthian. Doric columns form the peristyle while Ionic columns support the interior and a single Corinthian column features in the centre of the interior. The Corinthian capital is the earliest example of the order found to date.
The temple appears to have been forgotten for almost 1700 years until it was rediscovered in the 18th century and attracted intense interest from scholars and artists. The isolation of the site ensured many significant features survived largely intact. The temple is one of the earliest post-Parthenonian edifices and the earliest monument in which all three ancient Greek architectural orders – Doric, Ionic and Corinthian – are found together. It also included the earliest surviving Corinthian column capital. The temple further exhibits a number of bold and innovative architectural designs that mark a turning point in the development of temple-building. Through a series of ingenious devices, the architect successfully balanced contrasting elements and blended the old with the new, contributing to the unique architectural and artistic value of the monument. The temple, as well as its sculptural decoration consist one of the best-preserved samples of the ancient Greek civilization, from the period of its heyday (5th century BC).
The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
