Did Lara discover
the Antikithera device?
The Antikythera device was found in 1900.
Was the other device, the one she found, another version of it? Manfred Powell, as a member of the Illuminati, would have known that. But he was totally puzzled at the device Lara showed him pictures of. So, the answer to your question must be no.
