were built; nearly every polis, every Greek colony contained one or several. There were also temples at extra-urban sites and at major sanctuaries like Olympia and Delphi. The observable change of form indicates the search for a harmonious form of all architectural elements: the development led from simpler early forms which often appear coarse and bulky up to the aesthetic perfection and refinement of the later structures; from simple experimentation to the strict mathematical complexity of ground plans and superstructures. Decline of Greek temple building: Hellenistic period From the early Hellenistic period onwards, the Greek peripteral temple lost much of its importance. With very few exceptions, Classical temple construction ceased both in Hellenistic Greece and in the Greek colonies of Magna Graecia. Only the west of Asia Minor maintained a low level of temple construction during the 3rd century BCE. The construction of large projects, such as the temple of Apollo at Didyma near Miletus and the Artemision at Sardis did not make much progress. The 2nd century BCE saw a revival of temple architecture, including peripteral temples. This is partially due to the influence of the architect Hermogenes of Priene, who redefined the principles of Ionic temple construction both practically and through theoretical work. At the same time, the rulers of the various Hellenistic kingdoms provided copious financial resources. Their self-aggrandisation, rivalry, desires to stabilise their spheres of influence, as well as the increasing conflict with Rome (partially played out in the field of culture), combined to release much energy into the revival of complex Greek temple architecture. During this phase, Greek temples became widespread in southern Asia Minor, Egypt and Northern Africa. But in spite of such examples and of the positive conditions produced by the economic upturn and the high degree of technical innovation in the 3rd and 2nd centuries BCE, Hellenistic religious architecture is mostly represented by a multitude of small temples in antis and prostyle temples, as well as tiny shrines (naiskoi). The latter had been erected in important places, on market squares, near springs and by roads, since the Archaic period, but reached their main flourish now. This limitation to smaller structures led to the development of a special form, the pseudoperipteros, which uses engaged columns along the naos walls to produce the illusion of a peripteral temple. An early case of this is temple L at Epidauros, followed by many prominent Roman examples,
