Ok I am a week late with my X. Please forgive me I have been in France with my daughters and a son in law.
I was actually looking forward to contributing on X as I knew right from A that for X I was going to tell you about a biblical king called Xerses.
To find about Xerses the great you need to read Esther 1. Interesting character .
As I do not know him personally I do not feel able to make comments about him.
I am now off to find out what other people have contributed to Alphabet Thursday .
