52 × 105 m. A double portico of 8 × 21 columns enclosed the , the back even had ten columns. The front used differing column distances, with a wider central opening. In proportion to the bottom diameter, the columns reached three times the height of a Doric counterpart. 40 flutings enriched the complex surface structure of the column shafts. Samian column bases were decorated with a sequence of horizontal flutings, but in spite of this playfulness they weighed 1,500 kg a piece. The capitals of this structure were probably still entirely of wood, as was the entablature. Ionic volute capitals survive from the outer of the later rebuilding by Polycrates. The columns of the inner had leaf decoration and no volutes. Cycladic Ionic In the Cyclades, there were early temples entirely built of marble. Volute capitals have not been found associated with these, but their marble entablatures belonged to the Ionic order. The Artemision of Ephesos Roughly beginning with the erection of the older Artemision of Ephesos around 550 BCE the quantity of archaeological remains of Ionic temples increases. The Artemision was planned as a , its architect Theodoros had been one of the builders of the Samian Heraion. With a substructure of 55 × 115 m, the Artemision outscaled all precedents. Its was executed as unroofed internal peristyle courtyard, the so-called . The building was entirely of marble. The temple was considered as one of the seven wonders of the ancient world, which may be justified, considering the efforts involved in its construction. The columns stood on ephesian bases, 36 of them were decorated with life-sized friezes of human figures at the bottom of the shaft, the so-called . The columns had between 40 and 48 flutings, some of them cut to alternate between a wider and a narrower fluting. The oldest marble architraves of Greek architecture, found at the Artemision, also spanned the widest distances ever achieved in pure stone. The middle architrave block was 8.74 m long and weighed 24 metric tons; it had to be lifted to its final position, 20 m above ground, with a system of pulleys. Like its precedents, the temple used differentiated column widths in the front, and had a higher number of columns at the back. According to ancient sources, Kroisos was one of the sponsors. An inscription referring to his sponsorship was indeed found on one of the columns.
