What is a tribikos?

Answer 1

In brief, it's a three-beaked distillation column or still, originally designed by the Alexandrian alchemist Mary the Prophetess for distilling minerals and plants. This is used in serious alchemy, not the turning-lead-to-gold nonsense.

Answer 2

A tribikos is a type of ancient Greek distillation apparatus used for producing alcohol, specifically for distilling wine. It consisted of a sealed container that held the liquid to be distilled, a heating element underneath to heat the liquid, and a tube or pipe to carry and collect the distilled alcohol.
