Hermogenes of Priene (late 3rd - early 2nd century BC) was a Hellenistic architect, best known for designing a temple of Artemis Leukophryene (Artemision) at Magnesia in Lydia, an Ionian colony on the banks of the Maeander river in Anatolia.
In the winter of 1842-3, a French team struggled with swampy ground and a high water table at the heavily sedimented site, and succeeded in removing 40 meters of the temple's frieze, comprising 41 blocks, and some other architectural elements.
Since the 1980s, enough remnants of the U-shaped raised colonnaded altar that faced the temple have been recovered to permit modern reconstructions of its original appearance, for the first time since Antiquity.
It was the largest temple to Dionysus in the ancient world; only the platform (stylobate) remains, measuring 18.5 by 35 meters (61 by 115 feet).
It was constructed early in the 2nd century BC and later reconsecrated to the cult of Tiberius and partly rebuilt during Hadrian’s reign.
