Guidonian hand
In Medieval music, the Guidonian hand was a mnemonic device used to assist singers in learning to sight-sing. Some form of the device may have been used by Guido of Arezzo, a medieval music theorist who wrote a number of treatises, including one instructing singers in sightreading. The hand occurs in some manuscripts before Guido's time as a tool to find the semitone; it does not have the depicted form until the 12th century. Sigebertus Gemblacensis in 1105–10 did describe Guido using the joints of the hand to aid in teaching his hexachord. The Guidonian hand is closely linked with Guido's new ideas about how to learn music, including the use of hexachords, and the first known Western use of solfege.
Wand
Wands were introduced into the occult via the 1200s latin grimoire The Oathbound Book of Honorius. The wand idea from the Book of Honorius, along with various other ideas from that grimoire, were later incorporated into the 1500s grimoire The Key of Solomon. The Key of Solomon became popular among occultists for hundreds of years. In 1888, there was the publication of an English translation of the Key of Solomon by Samuel Mathers (one of the co-founders of the Hermetic Order of the Golden Dawn), which made the text of the Key of Solomon available to the anglophone world. That 1888 English version inspired Gerald Gardner- the creator of Wicca, to incorporate the wand and various other ritual objects into Wicca.
