It has been reported that the City of Luxembourg (which is not just a city, but a country in its own right) has commissioned a mermaid statue for its 1050th anniversary.
A well-known legend has it that Melusine was the wife of Count Siegfried, who founded Luxembourg in 963 with the acquisition of Luxembourg Castle. So a mermaid statue of Melusine is a splendid idea.
The Melusine legend exists in a number of versions across Europe, with similar elements. Essentially Melusine marries, but with the stipulation that once a week she must have absolute privacy. She turns into a mermaid every Saturday, and spends the time in a bathtub in complete privacy. One day, her husband can no longer contain his curiosity and spies on his wife while she is bathing, and sees her as a mermaid. At this point, she vanishes forever, although she is occasionally seen in the river.
I will report more on the Luxembourg statue as data becomes available.
