### About The Hyleg as Itself or as the Pars Hyleg (Part of the Hyleg)

#### Calculating the Hyleg

OK, you remember I said calculating the Part of the Hyleg was the EASY part? ;-) Here comes the FUN part -- figuring out the REAL Hyleg! The following material is my understanding of the methodology presented by Al-Khayyat (in the James Holden translation). To me, it appeared that Al-Khayatt took some shortcuts in his explanation or made assumption in the understanding of his students. I have attempted to clarify those in a way which made sense to me, however, it may be that my own understanding is flawed. For the serious students of astrology or a person with special interest in the Hyleg, you would of course try to refer to the original source.

Please note that you must use the standard table of dignities to answer many of these questions. This link will open a table of dignities in a separate browser window, so that you may easily go back and forth between this decision tree and the dignities.
