Archaeology can bring historical fiction writers the best stories. This one will fit in nicely as I write the second book of Spiral in Time. A working title is Spiral: Shaman's Mask, which continues the story of archaeologist Germaine O'Neill and her incredible voyage into the 5th Century BC and the life of her ancestor, Sabrann ap Durot.
The mass burial described in the link features nameless Celts, but it is still the kind of newly found gold historical fiction writers love to find. I can imagine stories to speak for these long-dead bones. It is a burial, however hastily made, and rituals surrounding burials change over time. The most informative are graves where symbolic or actual objects are included. Grave goods breath life into nameless people and teach us what they valued. This gorgeous gold necklace might have been found in the burial chamber full of rich artifacts in the first book of Spiral and would not have been unusual to accompany a high status queen on her journey to the Otherworld.
My interest sprang to life when I read about this strange grave finding in France. Was it a plague, a massacre? There is still a big question mark in my mind as my work in progress develops. But it's nice to have some open-ended situations to add to the book.
