Cheiro and Benham both give this curved marking on the outer edge of the palm the same name — the Line of Intuition — and both connect it to a heightened sensitivity to impressions.

This article covers where the two authors place the line, how each distinguishes it from its close neighbor the Mercury line, and their named historical associations — along with how Palmistry Path separates those associations from its own editorial policy. Cheiro’s account appears in both Palmistry for All (1916) and Cheiro’s Language of the Hand; Benham’s appears in The Laws of Scientific Hand Reading (1900).

Where to find it

The Line of Intuition sits on the outer, percussion side of the hand — the edge below the little finger — tracing a curved or near-semicircular path between the territory of the Mount of Mercury, near the base of the little finger, and the Mount of Luna, in the lower outer palm. Cheiro describes a roughly semicircular course running from the face of Mercury to Luna, sometimes appearing in a form confined to Luna alone; in Cheiro’s Language of the Hand he places the same near-semicircular curve running from Mercury toward Luna. Benham places it in the same general territory, described from the opposite direction: rising on the Mount of Luna, curving inward across the Plain of Mars, and ending on or near the Mount of Mercury.

A nearby look-alike is the Mercury line, also called the Health line or Hepatica, which runs through the same lower-to-upper palm territory toward Mercury. Benham’s distinguishing test is shape: the Mercury line runs straighter, while the Line of Intuition curves. Cheiro adds a complication worth knowing before you go looking for either: he notes the two markings can run through or alongside one another on the same hand while still remaining distinguishable lines, so a curve found near a straighter line in this region doesn’t necessarily mean you’re looking at only one feature.

What it’s traditionally associated with

Cheiro’s historical reading, consistent across both of his books, centers on sensitivity to impressions. He associates the line with a temperament unusually receptive to its surroundings — presentiments concerning other people, vivid dreams and warnings, a heightened impressionability, and an inspired quality in speech or writing that draws on that same receptivity.

Benham’s reading covers similar ground from a different angle: he associates a well-marked Line of Intuition with intuitive impressions and with sensitivity in estimating other people. Benham also gives a deep-versus-broken degree reading specific to this line: in his system, a deep, clearly formed line indicates more of that intuitive faculty, and a broken or poorly formed one indicates less. That is Benham’s own historical scale, stated specifically about this line — not a claim this article extends to depth or clarity on any other feature, and not an empirical measurement Palmistry Path treats as reliable.

Palmistry Path’s approach to this line

Both authors were writing in a period tradition that treats presentiment, intuition, and inspired impression as real faculties the hand can register. Palmistry Path presents their readings as exactly that: historical interpretations from two named classical writers, not evidence about how intuition or perception actually work. Having this line, on this site’s reading, doesn’t validate psychic or clairvoyant ability, and it isn’t a claim that any particular hunch, dream, or impression you have is accurate. The line describes a historical association with a certain kind of sensitivity — nothing here confirms whether that sensitivity, or any individual instance of it, is reliable.

Common myths

“A Line of Intuition proves you’re psychic.” Cheiro’s and Benham’s historical readings associate the line with a sensitive, impressionable temperament. Palmistry Path does not treat this line, or any palm marking, as evidence of psychic or clairvoyant power.

“No line means no intuition.” Absence isn’t covered by either author’s treatment of this specific line, and this article doesn’t extend their reading to a negative claim. A hand without a visible Line of Intuition tells you about the visibility of one particular marking, and nothing more should be read into it.

“If the line is there, your hunches are accurate.” Cheiro and Benham historically associate this line with a sensitive, impressionable temperament and intuitive impressions. Palmistry Path does not use this line, or any palm marking, to validate or guarantee that an impression, hunch, dream, or warning is accurate or reliable.

“It’s the same line as the Mercury line.” The two sit in the same general territory and, per Cheiro, can even run alongside each other — but both authors treat them as separate, distinguishable markings with their own names and readings, and Benham’s shape test still tells them apart: the Mercury line runs straighter, while the Line of Intuition curves.

Frequently asked questions

Is the Line of Intuition the same as the “Line of Clairvoyance”? The classical sources checked for this article — Cheiro and Benham — consistently name the feature the Line of Intuition. Neither establishes “Line of Clairvoyance” as a verified alternate historical name for it. Treat that phrase as a search term some readers use rather than a documented synonym from these two authors; other palmistry writing this article didn’t review may use it differently.

Does having this line mean I’m psychic or clairvoyant? Cheiro and Benham historically associate the line with a heightened sensitivity to impressions and surroundings. Palmistry Path does not treat this or any other palm marking as proof of psychic power, and does not use it to validate a clairvoyant or paranormal claim.

What if I don’t have a Line of Intuition? Neither author’s treatment of this specific line addresses its absence, so this article doesn’t offer a reading for a hand without one — only for what a visible line has historically been associated with.

How is the Line of Intuition different from the Mercury line? Both sit in the same lower-to-upper outer palm territory and can appear close together, but Benham distinguishes them by shape: the Mercury line runs straighter, while the Line of Intuition curves. Both authors treat them as separate, distinguishable markings with their own names and readings.

Does a deeper line mean stronger intuition? That’s specifically Benham’s own historical claim: he reads a deep, well-formed line as indicating more of the intuitive faculty he describes, and a broken or poorly formed one as indicating less. It’s presented here as his historical scale, not as an empirical measurement this site treats as reliable.

What comes next

For the mount that borders this line, see the Mount of Luna article, which covers the broader imaginative and intuitive territory Cheiro and Benham associate with that region. The minor lines overview is general context for how selected minor lines fit alongside the major lines and mounts; it does not currently cover the Line of Intuition by name.
