The article: "Encounters
with a Wichien Maas"
                                    
by Sue Brown
  She was a co-Author of "The Legend of Siamese Cats", that was a book translated in English about "Cat Book Poems" written in Ayuthea era, Thailand.
The book includes lots of old pictures of siamese cat, and plenty illustrations of ancient cats in Thailand.
(This is just an aside. She works a Rattery, now.)
 
 Incidentally, "Wichien Maas" means "the diamond of the moon" in Thailand.
Those cats were treasured as "the cat which brings the happiness" by the Thai people at the time.
