5th Century 

Epidamnus, a town founded by Greek colonists in 627 B.C., was East Roman Dyrrhacium when this post and lintel Byzantine Forum was built, probably after a big Dyrrhacium 5th century earthquake. Here the unfinished capitals of the cistern of Theodosius II are completely carved.  It was sufficient to have only a suggestion of the classical forms, greatly simplified. The leaves are just triangular overhanging bumps with acanthus motif and grooves. The column moldings, rounded out in earlier times, have become wide places on the shaft. This charming Byzantine style is almost "post-modern".

(Wiki): Here's a spot on duplicate found in the gardens of Aya Sophia at Constantinople.  During the fifth century, when the Durrës forum was being constructed, this design was the standard model of capital.  The marble workshop and sea transport industry was still going strong, "world trade" had not yet collapsed.
