The _Sposalizio_, or "espousals," or betrothing, is certainly a different
ceremony from the marriage. Is not the fact of young ladies popularly
considering and calling the third finger of the _right_ hand the engaged
finger, and wearing a ring on that finger when engaged, a confirmation of
your correspondent's idea, that at this "betrothal" or "espousals" (compare
the phrase "his espoused wife" of Mary before her _marriage_ with Joseph)
the ring was placed in the _right_ hand; at the marriage ceremony on the
left?
