Marcus Blepsius (Ethnian: Bzãrgã Plex) fl. 1570 – 1600, the most famous alchemist from the lands of what is now Ethnia, attempted to produce gold by the method of multiplicatio oculis.
this method required a specially prepared chamber containing a single bar of gold and a rapid shutter mechanism to allow sunlight to illuminate the gold for a brief instant. Blepsius would admit a pig, considered the greediest of animals in Ethnia, into the chamber, illuminate the gold and then attempt to rapidly enucleate the pig. the aim of this was to extract the gold temporarily transmuted within the eyeballs of the pig during the act of perception.
the Photoplex camera was named in his honour in the 1970s.
