During Alexanders time and his successors

During the time of Alexander's successors, the island of Kalymnos comes under the authority of Ptolemeos and Andigonos and the Selefkides. The island has also been under the sovereignty of the people of Rhodes.
Kalymnos acquires a special position in the Roman state by the emperor Agrippinas in 53A.D. when the Senate proclaims that Kos and Kalymnos would be free from taxation.

In 155A.D. though, a terrible event agitates the island. A massive earthquake that year, which destroyed Rhodes and Kos, struck Kalymnos, too.

After the definitive separation of the Roman empire into Eastern and Western, the island of Kalymnos belongs to the administration of Konstantinopolis but religiously remains under the jurisdiction of the Pope until 728A.D. when Leon the third, detaches it along with Greece, Crete and the islands of the Aegean Sea and hands it over to the Patriarchate of Konstantinopolis.
