The pentagrammaton () or Yahshuah () 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. The essential idea of the pentagrammaton is of an alphabetic consonantal framework Y-H-Sh-W-H, which can be supplied with vowels in various ways. (Also, the "W" can be converted into a "U" or "V", since the Hebrew letter ו waw writes either a [w] consonant sound—later on, pronounced [v]—or a long [u] vowel sound: see Mater Lectionis.) Renaissance occultism The first ones to use the name of Jesus something like "Yahshuah" were Renaissance occultists. In the second half of the 16th century, when knowledge of Biblical Hebrew first began to spread among a significant number of Christians, certain esoterically minded or occultistic circles came up with the idea of deriving the Hebrew name of Jesus by adding the Hebrew letter shin ש into the middle of the Tetragrammaton divine name yod-he-waw-he יהוה to produce the form yod-he-shin-waw-he יהשוה. This was given a basic Latin transliteration JHSVH or IHSVH or IHSUH (since there was no letter "W" or sh / [š] sound in Latin, and "I" and "J" were then not yet clearly distinguished as letters of the alphabet, nor were "U" and "V"). This could then be supplied with further vowels for pronounceability. By coïncidence, the first three letters of this consonantal transcription IHSVH, etc. were identical with the old IHS/JHS monogram of the name of Jesus (from Greek iota-eta-sigma). In Renaissance occultist works, this pentagrammaton (or five-letter divine name) was frequently arranged around a mystic pentagram, where each of the five Hebrew letters י ה ש ו ה was placed at one of the points (the letter shin ש was always placed at the upward-pointing vertex of the pentagram). One of the earliest attested examples of this diagram is in the Calendarium Naturale Magicum Perpetuum or "Magical Calendar" (published 1620 but dated 1582) of either Theodor de Bry (Flemish-born German, 1528–1598) or Matthäus Merian the Elder (Swiss, 1593–1650). The idea of the pentagrammaton was funneled into modern occultism by 19th-century French writer Eliphas Levi and the influential late 19th-century Hermetic Order of the Golden Dawn. The Golden Dawn favored the consonantal transcription IHShVH or YHShVH, and the pronunciation Yeheshuah. In
