Hippalus

Hippalus is credited by the Periplus of the Erythreaen Sea as the first to discover the passage from the Red Sea to India over the Indian Ocean

Hippalus (Ancient Greek: Ἵππαλος) was a Greek navigator and merchant who probably lived in the 1st century BCE. He is sometimes conjectured to have been the captain of the Greek explorer Eudoxus of Cyzicus' ship.
