Thank you to all who helped me with the two words "arckes" and "womtoes" I realise after Ann suggested womb rope that I had misread the letter "b" for "t" but the last part is not rope, but I'm sure that the definition of a girth strap would be correct. I was very interested in the descriptions of the "arks". It's great to have such knowledgeable and helpful persons in the list. Regards Liz Waring
