Calov Bible

The Calov Bible was made famous with the discovery of a long-lost copy that had once belonged to the composer Johann Sebastian Bach.

At the time of his death, the inventory of Bach's library specified ownership of Calovii Schrifften ("Writings of Calovius").

While a guest in the home of his cousin, Leonard Reichle, Riedel was shown a volume of the Bible in which he recognized Bach's signature on the title page.

In October 1938, Reichle donated the three volumes to the Concordia Seminary Library in St. Louis, Missouri.

The Calov Bible is in three volumes, each signed on its main title page by J. S. Bach, who followed his signature with the date, 1733.
