But there was a problem with the Uranometria as originally printed. For some reason, the tables were printed on the verso (back) of the appropriate plate, making it difficult to refer from plate to text without considerable flipping of pages. Indeed, if we look at a detail of the plate of Andromeda, we can see the star table showing through the printed page. Thus it was impossible to consult both chart and table simultaneously. In all later editions of the Uranometria, the versos of the plates were left blank, and the tables were printed separately. The first set of such tables was published in 1624; the copy on exhibit is a second edition.
