In the movie Troy (2004), the ships the Greeks use look more or less like the biremes of Classical times. What would Mycenaean galleys of the Late Bronze Age really have looked like?

In Shelly Wachsmann's book Seagoing Ships & Seamanship in the Bronze Age Levant (1998) he goes into a great amount of visual evidence for what Mycenaean ships looked like and draws upon ceramic vessels, murals, and even graffiti. Unfortunately, no Mycenaean shipwreck has been found yet unlike for other areas like the Uluburun or Kyrenia shipwrecks. All archaeologists and historians have at their disposal are iconographic representations. Mycenaean ships most likely looked very similar to something like this reconstruction based on interpretations of the icongraphic elements.
