Conflation, confusion, mixed motives, longing, faith, uncertainty, things strangely felt, and strangely garbled. A positive stew of Midrash and Bible and Quran and poetry and history. I loved this book. I don't think most people will, though, if I'm honest. But I ate it up.
On the surface this book is a fictionalized narrative a Jewish convert (or did he really convert?) to Islam named K'ab, who is a real historical figure. This man is obsessed with the rock of foundation at Mount Moriah, aka the Temple mount, and his son Ishaq with the help of a Christian builder, fashion the Dome of the Rock for the Caliph they serve.
K'ab is a storyteller and a story-seeker. The Rock is the epicenter of his storytelling.
This book takes faith and storytelling very seriously and examines the intertwined beliefs of Jews and Muslims and occasionally Christians as well, all in the 7th Century. It speaks of three Rocks: the rock of the K'aba, the rock of the Temple Mount, and the rock of Cavalry. But the Rock of foundation, of the temple mount, is decidedly the main character among the three.
This takes place during and after the Muslim conquest of Jerusalem and allows room for both genuine religion AND religious machinations among the three Abrahamic religions.
I found it mesmerizing. But if you don't like to be told dozens of strange stories about rocks and creation and cataclysm, cobbled together from Midrashic and Quranic sources, then you may not enjoy it as much as I did. The sources are like 50 pages long. The author took his time piecing together not only the fragments of history and thought, but even the natural phrasing of the time.
