Ptolemy III Euergetes
Lysimachus probably succeeded his father, not so long after the death of his father and after his father was honored by a decree from Ptolemy III Euergetes. When his father was honored by Ptolemy III in his decree to Telmessos, Lysimachus had a Greek Macedonian friend honored called Aristeas Kleandrou, who was given privileges in the Telmessian decree in accordance from a request in a letter that he had written. Lysimachus was the third ruler from the Lysimachid dynasty, which is also known as the Ptolemaic-Lysimachid dynasty in Lycia to rule the city. He was a contemporary to the rule of his paternal first cousin Ptolemy III Euergetes who ruled from 246 BC till 222 BC and one of the sons and heir of Ptolemy III, Ptolemy IV Philopator who ruled from 222 BC till 204 BC. He ruled as the second Ptolemaic Client King of Telmessos from 240 BC until he died in 206 BC.
