This book really does make Hildegard come to life, by presenting her in the context of her times and her beliefs. But there are lots of weird little historical mistakes that suddenly snap the reader out of 12th century Germany, making it hard to stay with the story line. For example: A monk says he thinks the nuns should just stick with their rosaries--but rosaries didn't exist then. The margravine is desribed as wearing a dress with lace at the sleeves, but lacemaking was still several centuries in the future. Bernard of Clairvaux is described as having a beard, but monks were clean-shaven--it was the friars of the next century that wore beards. And several characters supposedly wear velvet, but it hadn't been invented yet. I really wish the author had taken the time to research a little better, since Hildegard was (and is) such an appealing character. Historical novels that aren't true to their period are as annoying to read as stories with geographical or technological errors. Putting the archbishop in velvet is like putting Rome in France or giving President Lincoln a telephone--kinda makes it hard to believe the story after that.
