The Mount of Mercury sits at the base of the little finger. In classical palmistry, Mercury ruled commerce, communication, medicine, and the ability to connect with others — a broad portfolio that the god managed apparently without difficulty. Lines on this mount were interpreted according to which Mercurial trait they seemed most aligned with.
Short vertical lines — typically between three and five — on this mount were named "medical stigmata" in Victorian palmistry, which was nothing if not dramatic in its terminology. They were associated with healing aptitude, diagnostic sensitivity, and a deep empathetic connection with others' distress. Practitioners like Cheiro described them as extremely common among doctors, nurses, and healers of all kinds.
They are also common among teachers, therapists, social workers, parents, and — in my observation — nearly anyone who has ever sat with someone in difficulty and tried to help. Which either means the mark is an accurate indicator of caring aptitude, or that caring aptitude is widespread and the mark is common enough to appear in most people who exhibit it.
