The Reign of Terror is brought into focus in an unsettling and quite captivating way in “The Sky Over the Louvre,” our third book this week to consider in the NBM ComicsLit collection of Louvre-inpired books. Bernar Yslaire and Jean-Claude Carriere have created a most ambitious book here. The fight for liberty and justice championed by the Jacobins against the aristocracy was threatened by instability. Leave it to one mad zealot, Maximilien Robespierre, to pave the way to slaughter. This graphic novel provides great insight by balancing a story following the broad sweep of events along with intimate portraits.
