Valens II.23 (p. 175): “The Lot of Debt is calculated by determining the distance from f [Mercury] to S [Saturn] then counting that same distance from the Ascendant.”
“From Mercury to Saturn, projected from Ascendant” = Asc + Saturn − Mercury.
| day_add | day_sub | reverse_at_night | |

Valens delineation: Badly situated or ruler in opposition/square with malefics = native becomes a debtor. If related to Fortune, Accomplishment, or Daimon = livelihood from crime, deceit, force, or theft.
The former generic Debtor entry is now
Debt (Abu Mashar via al-Biruni): Asc + Mercury − Saturn by day, reversed
at night, from §476 row 12. The two formulas are retained under distinct
source-qualified names rather than treated as one disputed formula.
Valens V.1 (p. 409): “Consequently this place is strong; for day births it is found by determining the distance from S [Saturn] to h [Mars], then measuring the same distance from the Ascendant.”
Night births: “from h to S” = Asc + Saturn − Mars.
Formula: day = Asc + Mars − Saturn; night = Asc + Saturn − Mars → reverse_at_night=True.
PartDefinition("Accusation (Valens)", "Mars", "Saturn", True, "hellenistic")
Placement: After Accusation (Firmicus) in the catalogue.
Valens delineation: Malefics in aspect = precarious, endangered nativities; the sign defines the type of crisis. Benefics = lessening of evil or escape from crisis. Riley footnote also records an alternate tradition: “others measure the distance from Mercury” — a variant projector not yet in the catalogue.
Note: Accusation (Firmicus) = ("Saturn", "Mars", False) = day: Asc + Mars − Saturn — the same day formula but without night reversal. The day formulas are identical; Valens adds the night reversal.
Paulus Alexandrinus, PAG ch. 23, cited in Riley footnote (Valens p. 354):
“The Lot of Love/Eros is from Daimon to g [Venus].”
= Asc + Venus − Daimon = Asc + Venus − Spirit
No night reversal stated in the cited source.
PartDefinition("Eros (Paulus)", "Venus", "Spirit", False, "hellenistic")
Placement: After Eros (Olympiodorus) B, before Eros (Valens).
Relationship to other Eros entries:
Eros (Valens) = Asc + Spirit − Fortune (day). Operationally different — uses Fortune as subtractive, Daimon (Spirit) as additive.Eros (Paulus) = Asc + Venus − Spirit. Uses Venus directly rather than deriving from the lot pair.Paulus Alexandrinus, PAG ch. 23, cited in Riley footnote (Valens p. 354):
“The Lot of Necessity is taken from Fortune to f [Mercury].”
= Asc + Mercury − Fortune
No night reversal stated in the cited source.
PartDefinition("Necessity (Paulus)", "Mercury", "Fortune", False, "hellenistic")
Placement: After Necessity (Hermetic), before Necessity (Persian).
Relationship to other Necessity entries:
Necessity (Valens) = Asc + Fortune − Spirit (day). Operationally the inverse in structure.Necessity (Hermetic) = Asc + Fortune − Mercury (day). This is the reverse operand order from the Paulus formula; source text not yet verified.Valens II.24 (p. 176): “For day births, the position of the Lot is calculated by determining the distance from f [Mercury] to h [Mars], then counting the same distance from S [Saturn]; for night births, measure from h to f, then from S.”
The projector is Saturn, not the Ascendant. The source direction is Mercury→Mars by day and Mars→Mercury by night.
Current lots.py entry:
PartDefinition(
"Theft (Valens)",
"Mars",
"Mercury",
True,
"hellenistic",
projector="Saturn",
)
This computes:
PartDefinition.projector and the computation receipt’s projector truth now
carry this distinction directly. Theft (Olympiodorus) remains a separate,
Ascendant-projected entry pending its own source check.
Valens II.22 (p. 171): “The distance will not exceed the number 7 [≤7 signs] for night or day births but it is necessary to take the distance from the nearest Lot to the other Lot.”
Riley footnote: “Take the shortest distance between the two lots. This results in the Lot of Basis always falling below the horizon.”
PartDefinition.arc_policy = LotArcPolicy.SHORTEST now projects the unsigned
shorter interval between Fortune and Spirit from the Ascendant. Reversing the
source operands at night preserves the same unsigned interval, and the
computation receipt records the selected arc policy.
Valens II.30 (p. 197): “For night births, determine the distance from g [Venus] to the d [Moon] and count this distance from the Ascendant.”
Valens gives only a night formula. No day formula is stated. lots.py Mother = ("Moon", "Venus", True) uses the Valens night formula as the day formula and inverts it for night. Source for the day assignment is unverified.

Survey method: Full-document keyword scan for formula language (“count from,” “part of,” “lot of,” “from the degree of”), followed by targeted extraction of all formula-bearing sections:
Formula convention in Firmicus: Most lots stated as “count from X to Y and then from the Ascendant.” Day/night reversal is explicit when present (“by day… by night…”). Absence of qualifier + “always” = no reversal.

reverse_at_night False → True (FIXED 2026-04-19)Firmicus VI.32 §55 (p. 229): “If you wish to locate exactly the house of friends, by day count from Jupiter to Mercury, by night from Mercury to Jupiter.”
This is an explicit day/night reversal instruction. The existing entry had reverse_at_night=False, meaning the night formula was identical to the day formula.
| day_add | day_sub | reverse_at_night | |
|---|---|---|---|
| Before | Mercury | Jupiter | False |
| After | Mercury | Jupiter | True |
Day: Asc + Mercury − Jupiter (Jupiter→Mercury) ✓
Night (reversed): Asc + Jupiter − Mercury (Mercury→Jupiter) ✓
reverse_at_night True → False (FIXED 2026-04-19)Firmicus VI.32 §49 (p. 229): “If you wish to locate the house of travel, always count from the Sun to Mars and again from the ascendant.”
The word “always” (contrasting with §54’s “by day… by night…” for Enemies) signifies a single formula with no day/night inversion. The existing entry had reverse_at_night=True.
| day_add | day_sub | reverse_at_night | |
|---|---|---|---|
| Before | Mars | Sun | True |
| After | Mars | Sun | False |
Formula (always): Asc + Mars − Sun ✓
Firmicus IV.18 §1 (p. 141) in Bram: “in a diurnal chart count the degrees of every sign from the Sun to the Moon… that is the Part of the Daemon.”
This is identical to the Fortune formula (IV.17 §3). The standard Hellenistic formula for Daemon is Asc + Sun − Moon (day), the reverse of Fortune. This is almost certainly a translation error or manuscript variant in Bram. The correct Daemon formula (Asc + Sun − Moon, day; reversed night) is already correctly implemented in lots.py inline computation. No change required; note recorded for bibliographic honesty.
Firmicus VI.32 §48 (p. 229): “count from Mars to the Sun” — no day/night qualifier, no “always.” Formula: Asc + Sun − Mars.
lots.py entry has reverse_at_night=True. This may reflect a general convention (lots without explicit qualifier follow day/night reversal) rather than a Firmicus-specific instruction. The night formula (Asc + Mars − Sun) is not attested in Firmicus. Status: uncertain, not changed pending cross-reference with Dorotheus/Paulus.
Firmicus VI.32 §57 (p. 229): “count always from Mercury to the Moon” = Asc + Moon − Mercury, no reversal.
Slaves (Dorotheus) in lots.py: add=Moon, sub=Mercury, rev=True. The day formula matches Firmicus but the night reversal does not. No Slaves (Firmicus) entry exists. Since the entry is attributed to Dorotheus (not Firmicus), this may be intentional. To be verified against Dorotheus primary text.
Firmicus VI.32 §51 (p. 229): “count from the Moon to Jupiter” = Asc + Jupiter − Moon, no reversal stated.
No entry matching this formula with this attribution exists in lots.py. Courage = (Fortune, Mars, True) is a different formula. Courage, Violence & Combat = (Moon, Ruler Asc, True) is also different. A Courage (Firmicus) entry with ("Jupiter", "Moon", False) is absent. Not added in this session — the lot is unnamed in the text (“house of physical courage” is the translator’s label) and the lot name/attribution requires cross-reference before adding.
Firmicus VI.32 §56 (p. 229): “for the house of glory, count by night from Venus to Jupiter, by day the opposite.”
Night: Venus→Jupiter = Asc + Jupiter − Venus.
Day: Jupiter→Venus = Asc + Venus − Jupiter.
No Glory (Firmicus) entry in lots.py. Not added in this session — the lot name requires cross-reference to confirm this is the same concept as other “glory/fame” entries in the catalogue.

Note on Father (I.13): Dorotheus gives “from Sun to Saturn + Asc [by day]” = Asc + Saturn − Sun; then for night: “from Saturn to Sun, subtract from Asc” = Asc − (Sun − Saturn) = Asc + Saturn − Sun. Both resolve to the same formula; there is no day/night reversal in Dorotheus. lots.py Father = ("Saturn", "Sun", True) carries reverse_at_night=True, meaning lots.py follows a different tradition (Valens Book II.30 gives the same day formula; reversal may originate there). The lots.py entry is attributed broadly (“hellenistic,medieval”), not specifically to Dorotheus, so no correction is required; the discrepancy is doctrinal.
Note on Illness (Dorotheus): The formula is referenced in Dorotheus II.7 as a pre-existing lot (“the lot of illness”) but not defined there. No explicit definition was found in Books I, II, or III. The Firmicus cross-reference (Session 2, §40) confirms Saturn→Mars day / Mars→Saturn night, which matches the current lots.py entry. The Dorotheus attribution in the lot name remains unverified from Dorotheus primary text.
Note on Male Children operand direction (II.12): “Count what of degrees is between Jupiter and the Sun” — in Arabic astrological convention, “between A and B” = arc from A to B going direct. Arc from Jupiter to Sun = Sun − Jupiter → Asc + Sun − Jupiter. This matches lots.py ("Sun", "Jupiter", False). The companion entry Male Children (Dorotheus - Chinese) = ("Jupiter", "Sun", False) represents the reversed-operand reading and does not match Dorotheus II.12.
Dorotheus I.14 (Pingree p.174–175):
“Calculate the lot of the mother in a nocturnal birth from the Moon to Venus and in the daytime from Venus to the Moon, and add to it the degrees of the ascendent [by night] or subtract [it] from the ascendent [by day].”
Computation:
Both resolve to Asc + Venus − Moon with no day/night reversal.
lots.py Mother = ("Moon", "Venus", True):
The night formula matches Dorotheus. The day formula disagrees — Dorotheus says Asc + Venus − Moon both by day and by night; lots.py gives Asc + Moon − Venus by day.
Prior session cross-reference: Firmicus VI.32 §21–22 (Session 2) says “from Venus to Moon (day)” = Asc + Moon − Venus. lots.py follows Firmicus for the day formula, not Dorotheus.
Decision: No correction. The Mother entry is attributed broadly (“hellenistic,medieval”) and correctly reflects the Firmicus tradition. A Mother (Dorotheus) entry with ("Venus", "Moon", False) could be considered if doctrinal completeness requires it. Deferred — not added in this session.
Dorotheus II.3 (Pingree p.199): “If you want to see in the nativity of a woman the lot of marriage, then count from the degrees of Venus to Saturn and add to it the degrees of the ascendent.” No day/night qualifier.
Formula as stated: Asc + Saturn − Venus (always). Day formula matches lots.py ("Saturn", "Venus", True) day formula ✓. The reverse_at_night=True in the lots.py entry is not supported by Dorotheus II.3 alone — no night reversal instruction appears in this chapter. The reversal may come from another tradition (the men’s formula in II.2 has explicit reversal; women’s may be assumed symmetric). Document as observation. No correction in this session.
Dorotheus I.21 (Pingree p.180): “Count from the degree in which Mercury is to Jupiter, and add to it the degrees of the ascendent [by day] or subtract it from the ascendent thirty [degrees at a time] [by night].”
Day: Asc + Jupiter − Mercury. Night: Asc − (Jupiter − Mercury) = Asc + Mercury − Jupiter. This is a confirmed reversal.
lots.py entry (line 632):
PartDefinition("Siblings (Number)", "Jupiter", "Mercury", True, "hellenistic,medieval")
Day and night formulas now match the explicit Dorotheus I.21 instruction.
Resolution: The direct Dorotheus witness is sufficient for this Dorotheus-oriented correction; no broader cross-author equivalence is implied.
Dorotheus II.11 (Pingree p.209–210): “Count from Mars to Jupiter and add to it the degrees of the ascendent [by day] or subtract it from the ascendent [by night], thirty at a time.”
Day: Asc + Jupiter − Mars. Night: Asc − (Jupiter − Mars) = Asc + Mars − Jupiter. This is a confirmed reversal.
lots.py entry (line 679):
PartDefinition("Time of Children", "Jupiter", "Mars", True, "hellenistic,medieval")
Day and night formulas now match the explicit Dorotheus II.11 instruction.
Resolution: The direct Dorotheus witness is sufficient for this Dorotheus-oriented correction; no broader cross-author equivalence is implied.
Source presented: bonatti146.pdf — Anima Astrologiae, or A Guide for Astrologers: Being the One Hundred and Forty-Six Considerations of the Famous Astrologer Guido Bonatus. Translated from Latin by Henry Coley, 1675. William Lilly prefatory address dated 2 August 1675. Skyscript/STA scan.
Finding: Wrong Bonatti work.
This PDF contains the 146 Considerations (Anima Astrologiae) — a collection of horary and natal aphorisms, not a lot formula catalogue. It makes three references to the Part of Fortune as an interpreter’s significator in horary judgment (Considerations 85, 103, 122) and one generic formula for constructing an ad hoc lot from any two significators (Consideration 140: “subtract the lesser from the greater, and add to the remainder the degrees of the sign Ascending, and project what they amount unto from the Ascendant”). None of these define operand pairs for any named Arabic Part.
The required source is Liber Astronomiae (The Book of Astronomy), Bonatti’s full treatise. The Arabic Part formula catalogue is in the Liber Astronomiae, Part I (Tractatus I), specifically in his discussion of the lots — typically translated by Benjamin Dykes (2010, Cazimi Press). The 146 Considerations are an appendix / distillation abstracted from the larger work; they contain no lot formula tables.
Result: No lots.py entries verified or corrected this session. No changes to lots.py.

D11 — Debt naming / operand direction (RESOLVED):
The apparent contradiction came from collapsing two authorities. Valens II.23
gives Mercury→Saturn from the Ascendant without reversal. Abū Maʿshar’s table,
transmitted by al-Bīrūnī at §476 row 12, gives Saturn→Mercury and changes at
night. The catalog now preserves both as Debt (Valens) and
Debt (Abu Mashar via al-Biruni).
D12 — Illness (Ancients) sub-operand (RESOLVED):
The §476 row 31 glyph is Mercury, not Venus. The row gives Mercury→Mars and
“same,” matching Illness (Ancients) as Asc + Mars − Mercury with no night
reversal. No engine change was required.
D13 — Marriage (Men, Valens) reversal (RESOLVED):
Valens II.38 gives Sun→Venus for men without a night reversal. In the §476
table, the continuation mark was misread as “change”; it carries the preceding
“same” instruction. Marriage (Men, Valens) remains Asc + Venus − Sun,
reverse_at_night=False.
D14 — Marriage (Women, Valens) reversal (RESOLVED):
Valens II.38 gives Moon→Mars for women without a night reversal. The §476
continuation mark likewise means “same.” Marriage (Women, Valens) remains
Asc + Mars − Moon, reverse_at_night=False.
D15 — Knowledge direction and reversal (RESOLVED):
The unsupported generic Knowledge label was replaced with the exact
source-specific Knowledge, True or False (Abu Mashar via al-Biruni).
Section 476 row 61 gives Jupiter→Moon and “same”: Asc + Moon − Jupiter,
without reversal.
Alternate projectors and shortest-arc projection are now first-class engine policies. Ordinary house cusps and their rulers are also already resolvable, so rows 11, 50, 55, 86, and 91 are catalog-admission questions rather than proof of an engine limitation.
Three §476 patterns still need separately typed operand semantics before admission:
These patterns remain outside this doctrine-decision pass.
