This alphabet from 1780 contains yet another apparent Hooked X symbol for "a."
These are only nine of at least one hundred and twenty examples of the "X" symbol being used for the letter "a." Below is the only example I had previously seen of the "X" symbol used for "a" in a secret coded alphabet from a 15th Century Cistercian Germanic manuscript I published in my "Hooked X" book in 2009.
Two examples of complicated sigil drawings from the Icelandic manuscripts that incorporate runes and Masonic box code symbols (left), and a heavily Christian influenced drawing (right) that were both used for witchcraft and ritual magic.
These sigil drawings incorporate heavy Masonic symbolism (left) and what appear to be two Hooked X symbols in the upper right part of the upper arm (right).
One of the two Larsson Papers, dated to 1883 and 1885, using the same pentadic numbering system as found on the Kensington Rune Stone, which also contains two runic alphabets written in the "Secret Style." These alphabets which include the Hooked X for "a", along with the alphabetic box code were clearly Masonic and prove the Larsson Papers are related to both known medieval Cistercian secret coded alphabets and the recently published Icelandic secret alphabets that lean heavily on ancient runes.
These two examples of the Hooked X are found in medieval Icelandic manuscripts from 14th (Right, 1300-1400) and 15th Centuries (Left, 1490-1510).
This circa 6th century Anglo-Saxon brooch with eight symbols carved into the outer ring include a Hooked X at the 2:00 o'clock position. It was excavated next to a skull in Old Hunstanton, in Norfolk, England in 1900.
