West side (rear) of the Temple of Hephaistos, the Temple dedicated to Hephaestus and Athena Ancient Agora, Athens. Greece. Hephaestus and Athena are divinities of metalworkers and artisans. The Temple which crowns the Agoraios Kolonos hill overlooking the Agora was built between 450-415 BC; the build time was protracted as it was competing for workers due to the great period of rebuilding after the Persians wars. The temple, which is the best preserved of antiquity, has a marble Doric peristyle of 36 columns (6 by 13 columns) and is smaller than the majestic Parthenon although it shares the masterful optical refinements of the famous landmark.
