Alcocoden Calculator — The Giver of Years

What the alcocoden is

The alcocoden is the giver of years. It is not a separate search; it follows automatically from the hyleg. Whatever classical planet rules the sign the hyleg occupies becomes the alcocoden.

That ruler carries three possible year-values, its greater, mean and least terms. Which one it grants depends on where the alcocoden itself sits in the chart.

An angular alcocoden, placed in the first, fourth, seventh or tenth house, gives its greater years. A succedent one gives the mean, and a cadent one the least.

Condition then modifies the total. An alcocoden that is retrograde, or sitting in its fall, hands over only half its allotted years, a doubling-down the medieval manuals applied consistently.

How we draw the years

First we find the hyleg with the dignity count over the five aphetic places, exactly as the hyleg tool does. Its sign then fixes the alcocoden as that sign's domicile lord.

We locate that alcocoden in the natal chart and classify its whole-sign house as angular, succedent or cadent. The class picks the greater, mean or least year-term.

We check the alcocoden's condition. If it is retrograde or occupies the sign opposite its exaltation, its fall, we halve the term.

The probes pin the table and the logic. The least years must sum to 129, the mean must equal the average of least and greater, the greater years of the five wanderers must equal their Egyptian bound spans and sum to 360, and the halving must follow the angularity and condition consistently.

What the report returns

The calculator prints:

• The hyleg and the sign it occupies, and therefore the alcocoden.
• The alcocoden's house and its angularity, angular, succedent or cadent.
• The chosen year-basis and the base figure before any halving.
• The final years, flagged and halved when the alcocoden is retrograde or in fall, plus the full classical years table.

A worked example: Saturn grants the years

In the London night chart the hyleg is Mars, at about 28 degrees Aquarius. The ruler of Aquarius is Saturn, so Saturn is the alcocoden.

Saturn itself sits near 10 degrees Taurus, the eleventh whole-sign house, a succedent place. A succedent alcocoden grants its mean term, and Saturn's mean is 43.5 years.

But this Saturn is retrograde, and retrograde alcoden halves the count. So the 43.5 mean years fall to 21.75, the figure the tool prints for this example.

The table underneath shows where those numbers come from. Saturn's least term is 30 and its greater 57, so the mean, their average, is 43.5. Note that Saturn's greater years, 57, are exactly its total bound degrees across the zodiac.

How the years were used

The alcocoden's total was a starting measure, not a verdict. The tradition then subtracted or added through the apheta, the yearly lords, and through eclipses and hard transits bearing on the hyleg.

A greater-term alcocoden in an angular house was read as the most generous allotment, and a cadent, retrograde or fallen one as the meagerest, all within the symbolic logic of the technique.

The tie between the greater years and the bound spans is not a coincidence. Both come from the same underlying degree accounting, one planet's total bound degrees across the signs being reused as its maximum year-value.

Read carefully, the alcocoden shows how the older astrologers built a numeric scaffold out of pure dignitary rules, then hung a life-span narrative on it.

What this tool does not claim

This is a historical calculation, not a prediction of how long you will live. No length-of-life figure from any astrology should be treated as a medical or mortality forecast, and none is intended here.

We use the standard classical year-values and the angular, succedent, cadent rule with the retrograde and fall halvings. Authors differed on extra additions, subtractions and the direction of the lots, so your manual may show a different total.

The result is only as good as the hyleg, and the hyleg here is the summed-dignity proxy rather than the full ordered aphetic test. Different hyleg traditions can yield a different alcocoden.

Our method in one line

Positions come from sub-arcsecond astronomy (VSOP87/ELP via astronomy-engine), cast in Porphyry quadrant houses (whole-sign available on every chart). The alcocoden is the domicile lord of the hyleg's sign, granting greater, mean or least years by its own angularity, halved when retrograde or in fall, from a source-verified planetary-years table.

The probe pins the least-years sum of 129, the mean as the average, and the wanderers' greater years to their bound spans summing 360. Every worked-example figure is reproduced by that probe. Reviewed by Dr. Amara Osei, Astronomy Reviewer.
