I had never heard of this series, and I was perusing the shelves at a local bookstore, and chanced upon it. This was a series done by a couple of french-men (incidentally the same who started Metal Hurlant, which became Heavy Metal here in the USA.), Jean-Pierre Dionette and Jean-Claud Gal. It was published in comic form back in the 70's and has been released as graphic novels since. I picked up Vol 1 of Armies and have read through the first half of it. 

I was blown away by the draftsmanship of Jean-Claud Gal (unfortunately he died, only working on two series, this one, and one called Diosamante before his death), his backgrounds are stunning and I can see inspiration for Hyperborea architecture thrown in there for sure. The stories are intriguing, and have an odd bent to them, but they follow a "romanesque" legion for the first few issues and then a character called Arn. 

This is worth picking up, and i look forward to reading the rest of this, and getting the subsequent volumes in the series. I think it was published as a comic for around 17 years, so there is a ton of material here. 

Here is the amazon link for those interested.
