Upper Ancyle or Ankyle Kathyperthen (Greek, Ancient (to 1453);: Ἀγκυλή καθύπερθεν) was the name of a deme of ancient Attica. It was located east of Athens and bordering Agryle to the south.[1] Upper Ancyle passed from the phyle Aigeis to Antigonis in 307/306 BCE; Lower Ancyle remained in the Aigeis phyle.[2] [3]
In the 3rd century, in Roman times, the demoi were home to rich landed properties. Their name derives from the Greek name for "javelin" (which was thrown with a rope). The same root also appears in an epithet attributed to Cronus and to Prometheus, "of sharp wits".
The site of Lower Ancyle is located northeast of modern Ardettos.
