The temple was burnt down by Herostratos in 356 BCE and reerected soon thereafter. For the replacement, a crepidoma of ten or more steps was erected. Older Ionic temples normally lacked a specific visible substructure. This emphasised basis had to be balanced out be a heightened entablature, producing not only a visual contrast to, but also a major weight upon the slender columns. Temple of Apollo at Didyma The temple of Apollo at Didyma near Miletus, begun around 540 BCE, was another with open internal courtyard. The interior was structured with powerful pilasters, their rhythm reflecting that of the external . The columns, with 36 flutings, were executed as with figural decoration, like those at Ephesos. Construction ceased around 500 BCE, but was restarted in 331 BCE and finally completed in the 2nd century BCE. The enormous costs involved may have been one of the reasons for the long period of construction. The building was the first Ionic temple to follow the Attic tradition of uniform column distances, the frontal differentiation was not practised any more. Temple of Athena Polias, Priene Ionic were usually somewhat smaller and shorter in their dimensions than Doric ones. E.g., the temple of Zeus at Labraunda had only 6 × 8 columns, the temple of Aphrodite in Samothrace only 6 × 9. The temple of Athena Polias at Priene, already considered in antiquity as the classical example of an Ionic temple, has partially survived. It was the first monumental of Ionia, erected between 350 and 330 BCE by Pytheos. It is based on a grid (the exact dimensions of its plinths). The temple had 6 × 11 columns, i.e. a proportion of 5:10 or 1:2 intercolumnia. Walls and columns were aligned axially, according to Ionic tradition. The was of equal depth on all sides, eliminating the usual emphasis on the front, an , integrated into the back of the , is the first proper example in Ionic architecture. The evident rational-mathematical aspect to the design suits Ionic Greek culture, with its strong tradition of natural philosophy. Pytheos was to be of major influence far beyond his lifetime. Hermogenes, who probably came from Priene, was a deserving successor and achieved the final flourish of Ionic architecture around 200 BCE. The Artemision of Magnesia One of the projects led by Hermogenes was the Artemision of Magnesia on the Maeander, one of the first . other early include
