Skyscript Astrology Forum

I have a question concerning the transformation from Gadbury‘s charts to the round charts in your work: Some times I cannot replicate the charts. If the ascendant is correct, the moon is not and vice versa. Did you follow Gadbury‘s charts even when he made mistakes or did you use the nearest approximations with modern software?

Hi Georgius, the charts are as Gadbury shows them to ensure readers could follow his text.

Where I could find related chart info online, I give it in a footnote. I did try replications using Janus, generally ran them using his date and time and then rectified the chart to match his ASC and MC as closely as possible, most of the time, at least for his contemporary charts, planet positions were reasonably close; the older charts (before the 1600’s) were hit and miss.

Thank you for clearing!
The time you give in the pictures of the charts are the rectified times?

Hi Georgius ... no, the time shown in the charts is the time as Gadbury gave it.

Another question, sorry!
The frontispiece has two year dates: 1661 for the imprimatur and MDCIXII which reads as 1692 doesn’t it? Which data is correct for the time of publishing?

MDCIXII doesn't add up to a proper Roman number, but if you look closely, the first I is actually a lower-case L. This should be upper case: MDCLXII = 1662, the year of actual printing: 1661 was the year of the imprimatur, or permission to publish. (1692 would be written MDCXCII.)

Thank you, Martin!

Thanks for the catch Georgius, and the correction Martin; I've modified the page, currently replacing the file.

Thank you, Jane, for sharing such valuable and fascinating materials! The original book's printing really made reading challenging, and now having such a clear modern English version is truly reader-friendly!

That's a fantastic project — congratulations on completing it! Transcribing and modernizing a historical astrological text like this is no small feat.
