Peplon or Peplomer is a glycoprotein spike on viral capsid or viral envelope. They only bind to certain receptors.
A chi ton is a long woolen tunic worn in Ancient Greece, sorry I am not sure about the peplon! !! :)
In ancient Greece, both men and women wore chitons. Chitons were simple garments made of a rectangular piece of fabric draped over the body and secured with pins. Women also wore a peplum over their chiton, which was a shorter piece of draped fabric that added layers and decoration to their outfit.
