Lot of Eros
The Lot of Eros is a Greek lot for desire and attraction, computed from the ascendant, Venus and the Lot of Spirit. It belongs to natal character work, and traditional horary makes no use of it at all — we compute it and nothing in the judgment reads it.
The fuller picture
The formula in the Greek scheme is the ascendant plus Venus minus the Lot of Spirit in a day chart, reversed at night. That construction tells you two things straight away. It is a second-order lot, built on another lot, so any error in Spirit — including a mistake about whether the chart is diurnal — carries straight into Eros without warning. And its ingredients are Venus and the Sun-based lot of intention, which is why the Greek sources read it for wanting: attraction, appetite, what somebody is drawn towards, as against what actually happens to them.
Then the honest part, and it is the substance of this page. There is no horary doctrine for this lot. The English tradition that horary practice descends from carries the Part of Fortune and leaves the rest of the Greek lots in natal astrology. Across every worked chart we have gone through while sourcing this glossary — sixty-five figures from a modern working practitioner, including the historical charts he reproduces — Eros is never once used. The lots that do appear are Fortune, Spirit, Marriage, Children, Travel, Sickness, Death and a Part of Play. That silence is worth more to you than a paragraph of invented significance would be.
If you want to know what a romance question actually turns on, it is the ordinary machinery: the ruler of the first for the person asking, the ruler of the seventh for the other party, the Moon as co-significator, and the aspect between the two rulers with its reception. Desire, in a horary, shows up as reception and as the condition of those rulers. A lot cannot tell you something the rulers are silent about, and if the rulers make no contact then no lot supplies one.
The mechanical limits apply here as they do to every part. Eros is a computed address, not a body, so nothing about it applies or separates, no contact runs from it to a planet, and in this app the only contact it can register at all is a conjunction inside two degrees. Even that goes nowhere, because no rule reads it.
A fair use, if you want one: note it privately on a question about attraction, see whether it lands on a significator, and let the chart's own rulers give the answer. Do not present it as evidence.
In your chart
iHorary computes the Lot of Eros as one of the seven core lots and keeps it in the fuller planet enrichment data, but the chart page shows Fortune alone among the lots — a deliberate filter, added because the older list reported things like the Moon sharing a sign with Eros on a question about a job. No rule in the judgment engine reads Eros, so it never appears as testimony and can never affect a verdict.
