In 1535, Bernard Wapowski wrote a letter to a gentleman in Vienna urging him to publish an enclosed almanac, which he claimed was written by Copernicus. This is the first and only mention of a Copernicus almanac in the historical records. The almanac was likely Copernicus's tables of planetary positions. The Wapowski letter mentions Copernicus's theory about the motions of the earth. Nothing came of Wapowski's request because he died a couple of weeks later.
