Ptolemy's Table of Essential Digities and Debilities
Traditional Rulers of the Zodiacal Degrees

Only the visible planets and the Moon's nodes are considered by Ptolemy. The outer planets, asteroids, etc., have only been considered recently, since their discovery in modern times by means of the telescope. These newer chart factors, though worth considering, have no traditional dignity or debility.
Important note on degrees: there are 360 equal degrees in a circle, in this case the circle of the ecliptic. Each sign has 30 degrees; each degree is divided into 60 minutes; each minute is divided into 60 seconds of arc. For the same reason that there is no "Year 0" in the calendar (which begins with "Year 1"), the first degree of a sign contains 0�00'01"–1�00'00", the second degree contains 1�00'01"–2�00'00" and so on. 0�01' is in the 1st degree. 1�01' is in the second degree. 29�01' is in the 30th degree. It is essential to grasp this point.
The degree of exaltation is the degree stated. For example: the Sun is exalted in the 19th degree of Aries (i.e. between 18�00'01" and 19�00'00"). The terms are measured from the beginning of the sign to the degree of the planetary ruler indicated, then from the subsequent degree to the next and so on the the end of the sign. So for example, in Aries: the terms of Jupiter are 1�–6�; terms of Venus: 7�–14�; Mercury: 15�–21�; Mars: 22�–26�; Saturn: 27�–30�. Faces are assigned similarly.
