1579, "affinity between certain things," from M.Fr. sympathie, from L.L. sympathia "community of feeling, sympathy," from Gk. sympatheia, from sympathes "having a fellow feeling, affected by like feelings," from syn- "together" + pathos "feeling" (see pathos). In Eng., almost a magical notion at first; e.g. in ref. to medicines that heal wounds when applied to a cloth stained with blood from the wound. Meaning "conformity of feelings" is from 1596; sense of "fellow feeling" is first attested 1662. Sympathize "to have fellow-feeling" is recorded from 1605. Sympathetic "sharing the feelings of another" is from 1718. In anatomical sense, the word is attested from 1769, from Mod.L. (nervus) sympathicus, coined by Jacques-Benigne Winslow (1669-1760), Danish anatomist living in Paris.
