Both remind some of those built in the "3-body problem".
My pet peeve is that even at Antikythera times they could have, if they had knowledge, built electronic devices - copper wire needle contact with crystalized molten sand gives you a diode junction, add a wire - transistor, and leather, brine, copper disks - electricity.
There was a guy on youtube who used a kiln to smelt copper ore and zinc ore, made wire coils and a vinegar battery, and demonstrated a telegraph made with bronze age resources.
