Cornelius Duplicius Scepper (1500-1555) not only presented a beautiful book for publication in 1523--it was a work of deep scholarship, and it was edgy. Not skeptically-edgy, but a scientific-presentation-edgy, dismissive-via-the-facts-edgy.
The book (only two copies of which are found in libraries worldwide--at Brown and Oxford--though an online version is found here), Assertionis fidei adversus astrologos, sive signicationibus coniunctionum superiorum planetarum anni millesimi quingentesimi vicesimi quarti, was published in Antwerp for Franc. Byrckman on 16 May 1523. (The colophon at end describes the publication data so: "Symon Cocus, & Gerardus Nicolaus ... excudebant. Anno salutis humanæ MD.XXIII die xvi Maij. Impensis honesti viri Francisci Byrckmā ...")
The book evidently takes great and scholarly pains to point out any number of errors in miscalculations by astrologers, the weight of which and the diligence in historical presentation amounted to the book being a refutation of the claims of astrology. Among his many refutations is one that is quite simple and elegant: Scepper figures out that the starry firmament is at least 65 million miles from Earth, which means that the great vault is deeper and bigger still, and so given the size and the distance and the number of elements involved, it would be asking quite a bit of common sense to believe that all of that was having an effect upon the individual lives of Earthlings. Pretty good stuff for almost 500 years ago.
And just for the fun of it, here's a compilation video of tasty astrology debunkers, including Sagan, Dawkins, Tyson, Nye and Randi. Actually the James Randi part at about 4 minutes is absolutely priceless.
Notes:
Scepper also wrote a biography/history of Charles V: Rerum á Carolo V. Caesare Avgvsto in Africa bello gestarum commentarij elegantissimis iconibus ad historiam accommodis illustrati. Authorum elenchum, è
