I came upon this thread scanning through old posts. The nice thing about archives is that the threads never really die. Then again, maybe no one will notice I've even added to thread, but here goes.
I started with a gros of Philip le Bel, purchased to see if I had any interest in medieval France. It was okay, but still lacking something. My next purchase was a temple denier of Louis the Pious. Now I was getting interested. I knew I wanted to collect something French (the reasons had nothing to do with coins), so I defined a broad topic of Celtic Gaul through Medieval France. I supposed I would expand it into the present, so I thought I would focus on representative coins of rulers, periods, emperors, etc. As I began acquiring pieces, my interests became more refined.
Because of my archaeological research interests in prehistoric art and its role in religon, I decided to concentrate on coins with temples. That led me to a temple image on a Celtic coin of the Chartres region with the inscription PIXTILOS. I had already acquired a magnificient PIXTILOS coin with a bird eating berries out of a disembodied hand. Now I had two and an interest in who PIXTILOS might be. Lo and behold, Scheers had written an article on the 10 PIXTILOS varieties and their Republican Roman inspirations. Now I had a reason to add republican coins to the collection.
So, my themes emerged:
Celtic Gaul with an emphasis on the Carnutes region, specifically PIXTILOS varieties. Anything interesting (for my tastes) and well preserved.
Roman Republican models for Celtic coins in my collection and republican coins with Celtic themes (heads, armor, trophies, etc.).
Roman Empire coins minted in Gaul by emperor. Emphasis on temples or other religious themes such as altars, the chi-rho, Gallic wars, etc.
Merovingian and related representative coins.
Carolingian by type and emperor. Edict of Pitres cities for Charles the Bald.
Medieval coins of the region of Blois and Chartres with an abstract portrait dating to the period between 950 and about 1350.
I'm sure other interests will arise as time goes by, such as the coins of the period around the Blois-Chartres region, the royal coins of the same period, and the precursor types and types that immediately follow the bléso-chartraine period.
