The pentagrammaton (Greek: πενταγράμματον) or Yahshuah (Hebrew: יהשוה) is an allegorical form of the Hebrew name of Jesus, constructed from the original form of Jesus to be Yeshua, a Hebrew Bible form of Joshua. Originally found in the works of Athanasius Kircher, Johann Baptist Grossschedel (1619) and other late Renaissance esoteric sources.
