Live Long and Prosper

I remember Leonard Nimoy giving an interview on Public Television at which he talked about the hand sign used in Vulcan greeting. He remembered it from synagogue, where it was used for the Priestly Benediction of the congregation. He neglected to mention that only the kohanim (members of the priestly caste) were allowed to make the sign (something that my father taught me). However, whatever the traditions of Orthodox Judaism may be, I later found the same hand sign as part of a warm up exercise in a book about typewriter skills!
