Roman mosaic Stamp: Luxembourg Post

In the year 1995, Archaeological research undertaken at Vichten, Luxembourg resulted in the discovery of Roman villas.  Those Roman villas were made around 240 AD.  To commemorate this remarkable event, in the year 2007 Luxembourg Post issued a souvenir sheet depicting the unearthed mosaic which adorned the reception hall of one of the Roman villa. This mosaic stamp has the well-known Greek poet Homer and the Muse Calliope in the middle square box where as other eight muses surrounding them in four octagonal boxes and each box depicts 2 muses.  The muses' names are clearly seen in the stamp. (In the below stamp you can see Muse Polymnia).

Now this unearthed mosaic can be seen at the Luxembourg's National Museum of History and Art.
