How much of the *Iliad* was confirmed scientifically?

Question

Obviously, one of the central facts of Homer's Iliad was confirmed when archaeologists found Troy.

But were there any other details of Iliad (such as existance of Atreidae dynasty, Agamemnon actually having a military attack on Troy, existance of Odysseus as a ruler of Ithaca, etc...) that were confirmed scientifically - e.g. from reliable independent historical sources, archaeological finds, or other branches of sciences ^[1]

_{[1] - as a generic example of "other branches", astronomical confirmation of some celestial event mentioned, or some geological finds.}

Answer 1

In the story of the Trojan War, if not necessarily in the text of Homer's Iliad, Agamemnon's wife Clytemnestra learns of the fall of Troy via a relay of fire beacons. In Aeschylus' Agamemnon, she's said to have received the news in Mycenae (approximately 400 miles away) the very same night that Troy fell, and Aeschylus describes the path of the transmitted message. Two men in the 20th century, one a German historian and the other a communications engineer, each traced that path and deemed the relay as being feasible. This is briefly mentioned in James Gleick's The Information and described in somewhat greater detail here (see the section "Fire Beacons").

This may not meet the definition of scientific or archaeological confirmation, but it does lend some additional credence to the ancient texts.
