According to the book "Geographike Hyphegesis" written in 2nd-century Roman Empire, a Greek geographer Claudius Ptolemaeus mentioned about countries in the far east of the known world then. Among others is a city called "Argyre" on the western edge of the "Iabadiou" island. Iabadiou can be equated in Sanskrit as "Yawadwipa", which corresponds to the island of Java. The name "argyre" means "silver", while in local Indonesian and Sundanese language, silver is called "perak", which sound similar to the Merak port town on the western edge of Java.
