Pausanias, however (following Sosibius), interprets a long series of conflicts in Arcadia as stages in a gradual advance southward, ending with the conquest of Amyclae by King Teleclus (c. 800 B.C.) and of Helos by King Alcamenes (c. 770 B.C.).
War broke out - in consequence, it was said, of the murder of the Spartan king Teleclus by the Messenians - which, in spite of the heroism of King Euphaes and his successor Aristodemus ended in the subjection of Messenia to Sparta (c. 720 B.C.).
Archelaus' son Teleclus is said to have taken Amyclae, Pharis and Geronthrae, thus mastering the central Laconian plain and the eastern plateau which lies between the Eurotas and Mt Parnon: his son, Alcamenes, by the subjugation of Helos brought the lower Eurotas plain under Spartan rule.
