Meshech is Moscow: https://en.wikipedia.org/wiki/Meshech
Is it? According to myth and legend it says....no historical, geographical proof:
“Beginning from the 16th century, some European scholars proposed the idea that the Muscovites had stemmed from Meshech. Sir Walter Ralegh (c. 1616) attributes this opinion to Philipp Melanchthon (1497–1560) and to Benito Arias Montano (1571), and it was also followed later by Jonathan Edwards (1703–1758). Moreover, according to a legend first appearing in the Kievan Synopsis (1674),[2] Moscow (Moskva) was founded by King Mosokh son of Japheth (i.e. Meshech), and was named for him and his wife, Kva. In this legend, they are also said to have had a son, Ya, and daughter, Vuza, who gave their names to the nearby Yauza river.”
So Unicorns and Mermaids COULD be real afterall....not just myth and legend ;)
We have no actual proof, but we can just believe in myths and legends....oh heck that means fairies and leprechauns could be real also.
