The first written data about the island of Rab can be found in the works of ancient writers. But it is quite certain that the person on the island of Rab has lived a lot better. The findings of the late Paleolithic tools in the area of Lopar prove that the paleolithic man lived here, about whom there is very little information.
This Paleolithic prehistoric man was succeeded by the progressive Neolithic immigrants, but at the end of the Neolithic, Libumi settled so that the real prerequisite is that at that time the present port and the place Rab began to emerge.
The oldest data about the island of Rab can be found in the writings of a few Greek and Roman geographers. In these writings, Rab is mentioned by the names Arba, Arva, Arbia, Arbitana. The origin of this name can not be determined with certainty, but it is assumed that in the translation of the Indo-European root ARB, this would mean dark, dark, woody, which is characteristic of this island today. This name has been adopted by today’s inhabitants, Slavic Croats, the spirit of their language and changed it in Rab.
It is likely that the name of Rab dates back to the 7th century AD, or immediately after the arrival of the first Slavs on the island, however, the oldest known document, in which one finds the Croatian name, Rab, the Latin certificate on the founding of the Monastery of St. Euphemia (Sv. Eufemije), where a museum is preserved and dates back to the 15th century.
