Word of the day "Boustrophédon"

The glossary of architectural terms in Sainte Chapelle had the splendid word boustrophédon which is just too brilliant a word not to have a word of the day. One of the glorious stained glass windows in the chapel tells the biblical story it depicts in the backwards and forwards snaking pattern following an ancient writing pattern. Read more about it in English or French. Interestingly when it was used the forms of the letters going back would also change - making reading quite a challenge.
Meanwhile I should admit that architentural terms are really not my best suit in terms of vocabularly, so I was very thankful for the Sainte Chapelle's glossary.
