antiquity in the foundations of the circular tholos at Epidaurus was recovered during modern archaeological campaigns. Its enigmatic presence and preservation have been explained as a sculptor's model for stonemasons to follow in erecting the temple dedicated to Asclepius. The architectural design of the building was credited in antiquity to the sculptor Polykleitos the Younger, son of the Classical Greek sculptor Polykleitos the Elder. The temple was erected in the 4th century BC. These capitals, in one of the most-visited sacred sites of Greece, influenced later Hellenistic and Roman designs for the Corinthian order. The concave sides of the abacus meet at a sharp keel edge, easily damaged, which in later and post-Renaissance practice has generally been replaced by a canted corner. Behind the scrolls the spreading cylindrical form of the central shaft is plainly visible. Much later, the Roman writer Vitruvius (c. 75 BC – c. 15 BC) related that the Corinthian order had been invented by Callimachus, a Greek architect and sculptor who was inspired by the sight of a votive basket that had been left on the grave of a young girl. A few of her toys were in it, and a square tile had been placed over the basket, to protect them from the weather. An acanthus plant had grown through the woven basket, mixing its spiny, deeply cut leaves with the weave of the basket. Claude Perrault incorporated a vignette epitomizing the Callimachus tale in his illustration of the Corinthian order for his translation of Vitruvius, published in Paris, 1684. Perrault demonstrates in his engraving how the proportions of the carved capital could be adjusted according to demands of the design, without offending. The texture and outline of Perrault's leaves is dry and tight compared to their 19th-century naturalism at the U.S. Capitol. A Corinthian capital may be seen as an enriched development of the Ionic capital, though one may have to look closely at a Corinthian capital to see the Ionic volutes ("helices"), at the corners, perhaps reduced in size and importance, scrolling out above the two ranks of stylized acanthus leaves and stalks ("cauliculi" or caulicoles), eight in all, and to notice that smaller volutes scroll inwards to meet each other on each side. The leaves may be quite stiff, schematic and dry, or they may be extravagantly drilled and undercut, naturalistic and spiky. In Late Antique and Byzantine practice, the leaves may
