Each of the gene segments within the 2009 H1N1 influenza virus have been found in pigs for more than 10 years prior to the beginning of the 2009 H1N1 influenza outbreak. Pigs have long been considered a possible mixing vessel for influenza viruses that originate within pigs, birds and humans.
The art of the ancient Greeks and Romans is called classical art. This name is used also to describe later periods in which artists looked for their inspiration to this ancient style. The Romans learned sculpture and painting largely from the Greeks and helped to transmit Greek art to later ages.
Classical sculpture is simple, balanced, and restrained; the expression of a classical figure is composed and solemn. Hellenistic sculpture (ca. 330 BC-0), on the other hand, is typically dynamic and extravagant, with passionate expression; this aesthetic, which stands opposite to classicism, is known as baroque. 1.
