I added a description of the Regiomontanus housesystem to the Houses project. Regiomontanus was for a long period a popular system and it certainly is worth the effort to study it.
Did you know at least 70 house systems do exist? Some of them are well known but most of these systems are hardly ever mentioned. I would consider it a serious loss for astrology if knowledge about these systems would disappear. They are part of our astrological heritage and therefore deserve it to be remembered.
I will make an attempt. Starting today you will find at RadixPro an overview of house systems. I was able to locate 70 of them but that number will probably rise. I made a description – including formula’s and a calculation example – for five systems in the Project Houses. I will also describe the remaining systems. That will be on a regular base but it will take several years before I finish the description of all 70 systems. Apart from the description of the systems you will also find an annotated reference and an overview of the systems. In the future I will also add general articles on houses.
