Pelops

In an effort to study Human physiology and evolution, research presumably geared toward improving Goa'uld hosts, Pelops implanted the people settled on Argos with a nanovirus that aged everyone one year in the space of a single night. The virus was transmitted through physical contact, and when Col. O’Neill unknowingly married Kynthia, an Argosian woman, he was infected on his wedding night and consequently aged at a rapid rate. The source of the aging was identified and the controller for the nanovirus discovered in the base of Pelops’ statue. Once the device was deactivated, the Argosians began to age naturally and O’Neill was returned to his correct physiological age.

Pelops had not made an appearance at Argos for a very long time, and while the Argosians were initially horrified at destroying the image of their god, once they understood what was being done to them by the nanoviruses Pelops gave them, the Argosians embraced Pelops’ downfall and rejoiced in their freedom from his tyranny.
