Hermes Settings for Hellenistic Study: Whole Sign and Fortune

Begin a Hellenistic study in Hermes with three entries in your notes: which author and passage you are reading, where you start counting places, and which Fortune formula you use. Changing those choices can change the structure you interpret, even with the same chart data.

Start by counting the rising sign as the first place in Whole Sign, then compare a quadrant division from the same source data. Calculate Fortune as a point before examining places counted from it. Finding Fortune’s longitude and making Fortune the house reference are separate operations.

The setup proposed here is intended particularly for studying Fortune as a reference in Valens and comparing place divisions.

Where does the first Whole Sign place begin?

In Hermes, Whole Sign, code W, begins at the start of the sign containing the Ascendant. Each place occupies a complete sign. The exact Ascendant degree remains a separate value.

For an Ascendant at 18° Leo = 138°, the first place starts at 0° Leo = 120°, the second at 0° Virgo and the third at 0° Libra. An Ascendant of 18° Leo does not make that degree the beginning of the first place.

In this example the tenth place starts at 0° Taurus. With a Midheaven at 12° Taurus, the exact angle is 42°, while the tenth-place beginning is 30°. Record the start of a place separately from the angle’s degree within it.

Swiss Ephemeris §6.2.5 defines Whole Sign this way. A modern software option’s name alone does not establish that every ancient passage uses “place” for precisely the same calculation. Examine what the passage divides.

What does a quadrant comparison reveal?

Counting places from the rising sign and dividing arcs between exact angles such as the Ascendant and Midheaven use different geometries. A planet’s house number can change while its zodiacal degree stays fixed.

Valens’s Anthologies III.2 describes a degree calculation using thirds of the Ascendant–IC and Midheaven–Ascendant arcs. It can be read in the annotated reformatting of Riley’s translation, pages 244–246. The passage shows angle degrees being examined separately; it does not establish the modern Porphyry menu option as the single house system of the entire work.

In Hermes, Porphyry, code O, provides a useful geometrical comparison. Placidus, code P, is another quadrant comparison; do not present its name as the historical label for this Valens passage.

For geometry only, choose Ascendant 138°, Midheaven 42°, IC 222° and Descendant 318°. The Midheaven-to-Ascendant arc is 96°; the Ascendant-to-IC arc 84°. Dividing each into thirds gives 32° and 28°:

The planet in the final row remains at 10° Virgo in both columns. What changes is the boundary used to assign its house. These are teaching examples constructed from selected angles, rather than calculated chart results for a particular date.

Instead of recording only “planet in house 1,” state which division places it there. You can then ask which information your chosen passage uses, without combining two different house numbers into one reading.

How do you separate Fortune’s formula from sect?

Fortune / the Lot of Fortune is a point derived from the Ascendant, Sun and Moon longitudes. It is not a physical body. Sect here distinguishes a day chart from a night chart; the clock merely saying morning or evening is insufficient.

Hermes determines sect from the Sun and actual celestial-angle references, rather than reading a planetary house number. The Fortune formula preference is evaluated separately:

normalize returns an angle from 0° inclusive to 360° exclusive. Using the fixed formula does not turn a night chart into a day chart. It changes the expression used for Fortune; other techniques retain their own sect definitions.

For arithmetic, take Ascendant 138°, Sun 100° and Moon 235°:

• Day expression: 138 + 235 − 100 = 273° = 3° Capricorn.
• Night expression: 138 + 100 − 235 = 3° = 3° Aries.

Using the same numbers in both expressions demonstrates the formula difference; an actual chart’s sect must be established separately. Here the two results are 90° apart by the short arc. Do not assume the day and night expressions always give opposite points.

Why record Ptolemy’s rule separately?

The main text of F. E. Robbins’s translation of Tetrabiblos III.10 takes the Sun-to-Moon distance in zodiacal order and projects it from the Ascendant by both day and night. In modern longitude notation, that gives Ascendant + Moon − Sun. The LacusCurtius transcription, pages 275–277 and notes 59–61, supplies the rule and an editorial discussion of transmission differences.

The Hermes fixed preference lets you investigate that expression. One author’s rule should not become a universal claim about every Hellenistic writer. Record “Robbins main text, III.10; fixed expression” or “sect-dependent expression” to identify the method you follow.

This distinction can change more than a few minutes of longitude. In the example above, the formula choice moves Fortune from Capricorn to Aries, changing the starting sign for places counted from it too.

What does making Fortune the first reference do?

In “The Lot of Fortune as the Ascendant,” Valens considers Fortune as a separate reference together with the tenth, seventh and fourth places counted from it. The reformatted Riley translation, II.17, pages 124–125, also marks the section 17K/18P. Chapter numbering differs between editions, so record the title and page as well.

That passage supports the idea of counting places from Fortune. The distinction between the sign beginning and exact degree in two nearby Hermes choices requires a separate product definition:

For Fortune at 3° Capricorn = 273°, the first begins at 270° and the second at 273°, each constructing twelve houses at 30° intervals. Fortune is the same source point in both views. With its formula unchanged, selecting the reference alone does not change Fortune’s longitude.

Take an example planet at 2° Capricorn = 272°:

The planet retains the same longitude throughout. Its changing place number follows from the new reference. A first cusp based on Fortune does not physically relocate the Ascendant through a new calculation of the sky.

The Valens passage alone does not establish historical equivalence for every detail of these two modern options. Identify the purpose of the passage’s counting method, then record which product definition you compare with it.

How can you organise a Hellenistic study setup?

This starting setup is intended for examining Fortune as a reference in Valens and comparing house divisions:

Tropical is the starting choice for this exercise, rather than a universal historical assertion about every ancient author’s zodiac. Record the node type and other settings and keep them unchanged during the first comparison.

Compare W and O first. Then investigate the Fortune reference from the same data with the same Fortune expression. If you use a saved-settings slot, add the author/passage and formula to your notes. The label “Hellenistic” alone cannot reproduce a calculation.

How can you compare day and night examples?

For synthetic study data, choose 20 March 2000, 41° north, 29° east; Gregorian calendar. Make separate calculations for 12:00:00 UTC and 00:00:00 UTC. Convert appropriately if the form expects local time, and verify the resulting sect for each chart. Use the two instants as an exercise and record the calculated results separately.

1. Compare W and O at the first instant. Keep the inputs, zodiac, cusp setting, transformation and Fortune expression fixed. Record planetary longitudes separately from house numbers.
2. Retain exact Ascendant and Midheaven degrees. Distinguish them from the beginnings of the first and tenth Whole Sign places.
3. Check Fortune against its formula. Record the Ascendant, Sun, Moon and actual sect, and identify the expression chosen.
4. Open Fortune references from the same source. Compare the first cusps of ROTW:FORTUNA and ROT:FORTUNA. Do not reuse the previous derived result as a new source.
5. Calculate the second instant independently. Do not carry over the previous Ascendant, Moon or sect; those inputs can change with time.
6. Try the fixed preference separately. Follow the changed Fortune expression and its associated house reference. Do not assume the sect rules of other techniques have also changed.

If the required Fortune reference cannot be calculated, Hermes includes a fallback to equal houses with a warning. Check the house system actually returned, rather than relying only on the menu option selected.

Keep author/translator, work/chapter/page, study purpose, date–UTC–place, source zodiac, house system/cusp setting, sect, Fortune expression and longitude, first reference cusp and program version. Interpretations in the texts belong to their teaching frameworks; the exercises here compare calculations and references.

For distinguishing saved preferences from new-chart defaults, see the Hermes Chart Settings guide. A useful note identifies which passage you chose the setting to investigate.
