Two of Gavin Menzies‘ specific claims are that transoceanic travel began 100,000 years ago and that the Chinese regularly began visiting America from 2200 BC!
Dr Anton Mifsud has used the reign of King Ninus of Assyria as an anchor for his preferred date for the destruction of Atlantis (Malta) of around 2200 BC. He points out  that Eumelos of Cyrene dated the demise of Plato’s island to the reign of Ninus and links this with the calculation of the Roman historian Aemilius Sura (2nd cent. BC) who placed the reign of Ninus around 2192 BC. Several other authorities attribute similar dates to his reign as recorded by John Jackson in volume one of his 1752 Chronological Antiquities [1555.251].

In 2001, Tom Slattery published a paper(a) regarding the Comet Hale-Bopp which had been discovered 1n 1995. He speculated that it may have been seen much earlier in 2213 BC and that a fragment of it may have struck the Earth with dire consequences and may have been the trigger for the widespread collapse of civilisations around 2200! While comets are traditionally considered to be harbingers of doom, they certainly were in this instance when “thirty-nine members of the Heaven’s Gate cult committed mass suicide in March 1997 with the intention of teleporting to a spaceship which they believed was flying behind the comet.”(b)
