Superbly decorated Athenian pottery, for example, was widely dispersed along the trade routes of the Mediterranean, and the Romans made good quality pottery available throughout their empire through the manufacture and trade of the standardized red ware called terra sigillata, which was produced in large quantities at several sites in Italy and Gaul.
However, recent studies have challenged this view. Antibiotics proved to be a major improvement on antiseptics—which killed human cells along with bacteria—and their use spread rapidly throughout the 20th century.
Antibiotics like penicillin, vancomycin, cephalosporin and streptomycin have gone on to fight nearly every known form of infection, including influenza, malaria, meningitis, tuberculosis and most sexually transmitted diseases.

The pace quickened in the subsequent millennium, distinct new civilizations arising in Crete and Mycenae, in Troy and Carthage. And major trade routes such as the Silk Road paved the way for massive growth throughout Afro-Eurasia. To reach this temperature, furnace construction had to be improved and ways devised to maintain the heat for several hours.
