Caption: "Les Tres Riches Heures du Duc de Berry, Mars (i.e., March), Musee Conde, Chateau de Chantilly. Chateau de Lusignan." The Chateau de Lusignan is in the background.
The month is March as lunette shows---if you can fathom the funky lettering.
The lunette shows a lot of calendrical detail that is all rather complex to us---but it meant a lot to the Medievals.
But we can see that the wagon of the Sun passes from being in the sign of Pisces to being in the sign of Aries.
The zodiac constellations were located in those zodiac signs, more or less, about 2000 years ago, and gave the signs their names.
