The truth is ,
Adulis (Musnad: 𐩱 𐩵 𐩡 𐩪, Ge'ez: ኣዱሊስ, Ancient Greek: Ἄδουλις[1]) was an ancient city along the Red Sea in the Gulf of Zula, about 40 kilometers (25 mi) south of Massawa. Its ruins lie within the modern Eritrean city of Zula. It was the emporium considered part of the D’mt and Aksumite empires. It was close to Greece and the Byzantine Empire, with its luxury goods and trade routes. Its location can be included in the area known to the ancient Egyptians as the Land of the Gods, perhaps coinciding with the locality of Wddt, recorded in the geographical list of the Eighteenth Dynasty of Egypt.[2]

Aksum is mentioned in the Periplus as an important market place for ivory, which was exported throughout the ancient world:
From that place to the city of the people called Auxumites there is a five days' journey more; to that place all the ivory is brought from the country beyond the Nile through the district called Cyeneum, and thence to Adulis.

According to the Periplus, the ruler of Aksum was Zoscales, who, besides ruling in Aksum also held under his sway two harbours on the Red Sea: Adulis (near Massawa) and Avalites (Assab). He is also said to have been familiar with Greek literature:
These places, from the Calf-Eaters to the other Berber country, are governed by Zoscales; who is miserly in his ways and always striving for more, but otherwise upright, and acquainted with Greek literature.
