What is this?

In Christian Kabbalah, Johann Reuchlin (1455–1522) considered the 72 names - made pronounceable by adding the suffixes "El" or "Yah" - to be the names of angels: individuated products of God's will. He lists these "72 Angels of the Shem HaMephorash" in his De Arte Cabbalistica (1517), which greatly influenced later Hermetic works including those of the Golden Dawn. More info on the Shem HaMephorash wikipedia page.
