Rod of Aesclepius
In the United States the Rod of Aesclepius became conflated at some point with the Caduceus; the latter being the traditional symbol of Mercury/Hermes, god of roads, commerce and thieves, and the former the traditional symbol of the Greek god of healing and dreaming. Some speculate whether this erroneous attribution was an accident or intentional. Either way, it would explain the commercialization of the health care industry. Both symbols are still in widespread use. While the medical profession continues to use the Caduceus as its preferred symbol, the Rod of Aesclepius is also widely used by nurses, chiropractors and other healthcare providers. The Caduceus can also be found in banks and financial districts.
Hygeia? Iris? It is sometimes difficult to identify the goddesses represented in the works of artists of the Beaux-Arts movement in the US. While here she holds a Caduceus and not a Rod of Aesclepius, this may have been due to the widespread confusion at the time.
Artist: (Presumed) Arthur Brown Jr. (1874-1957)
These Caducei are all found on either medical buildings or those dedicated to commerce.
