Triptolemos (Τριπτολεμος) was a god of farming, made god by Demeter. When Hades kidnapped Persephone, daughter of Demeter, Demeter looked for her daughter everywhere. One night, she slept at King Keleos's palace, who was Triptolemos's father. Demeter, to show that she was grateful, decided to give immortality to Demophon, son of Keleos. However, she was interrupted in the rite by Queen Metaneira, wife of Keleos, so Demophon couldn't become immortal. Instead, Demeter gave immortality to Keleos's other son, Triptolemos. Triptolemus became the god of farming, and Demeter gave him a chariot driven by two serpents.
