Regards to everyone! :)

My question is about history of Astrology.
When was introduced circle wheel in western Astrology and why?
For simple pratical matters or other else?

Thanks in advance!

This has been discussed on Skyscript before, although I cannot say exactly when or in which thread. Circular charts have been around for a long time (see here, for instance), but were popularized during the 19th and early 20th centuries. You will find some information on pp. 5-6 of this article.

Many thanks, Martin! :)
The articles are very interesting! *.*

It's real particular the circle wheel in Greek Horoscope (first article) and the trasformation in square wheel. So, it's possible that circle wheel was used already in early time.

The circle wheel is "re-introduced" for pratical motifs (disposition of degrees, ciclicity of sky and so on) or mere estetic reasons?

Thanks again.

Here is the earlier discussion thread I think Martin was referring to. However, its more focused on when medieval square charts gave way to modern circular charts:

The article by Deborah Houlding Martin has given a link to above demonstrates conclusively that circular charts are present in the earliest preserved horoscopes.

Thanks, Mark. Yes, that was the thread I was thinking of.

Oxley obviously thought it was a matter of great practical significance.

Thank you Martin for sharing your "Worsdale and Oxley" article; indeed, quite interesting.
