sentences:  An ancient etymology based on mere similarity of sounds linked "pelasgos" to "pelargos" ("stork") and postulates that the Pelasgians were migrants like storks, possibly from Egypt, where they nest.Aristophanes deals effectively with this etymology in his comedy "The Birds".One of the laws of "the storks" in the satirical cloud-cuckoo-land, playing upon the Athenian belief that they were originally Pelasgians, is that grown-up storks must support their parents by migrating elsewhere and conducting warfare.
