Abstract: The rosary key is a one-piece, hand-held device to prompt the recitation of the rosary. Critical elements of the traditional rosary pendent are evoked by tactile design. The counting of a decade of Hail Marys is measured by the finger movement of a bead-like button through the ten “stops” of the channel. The “Our Father” or Lord's Prayer, preceding each decade, is recited while fingering a separate rotating bead. Fingering of button and bead serve to preserve the essential contemplative nature of traditional rosary use. Furthermore, the rotating bead, in independent function, prompts use as a pocket or keychain comfort/prayer object, meditative through repetitive fingering alone.
