Sigil magick has been in existence for millennia as drawn on cave walls during the Stone Age. Pictographs and ideograms were used as depictions showing successful hunts and other examples of life during the Neolithic period. There has been some speculation that early man used these not only to reflect previous hunts but as prayers or spells to ensure successful hunts or the future.
From the area of the Fertile Crescent, Turkey, Syria, Greece to India, China, and to ancient Egyptian hieroglyphs, glyphs, runes, and sigils have been used and found on every continent on earth and used to convey ideas and actions. During centuries that are more recent, sigils have been used most often as representations of angels, demons, and magickal intent. There are many existing sigils used by Jews, Germanics, Italians, Egyptians, and more.
Even with all the existing sigils from various sources, some witches still choose to create their own sigils, which have special meanings in their own life and craft. Some are based on the intent behind the magick, some based on the witches name to increase their power. Each sigil has its own unique power when it is created by the witch, according to the power and intent entered into the sigil upon its creation.
Sigils are used as components in spells, etched into candles, drawn on parchment, or fashioned into amulets and talismans worn by the caster or given as gifts. The manner of creation for personal sigils is open to the interpretation of the creator.
One method is to write down a particular phrase to express magickal intent. For example, bring me health.
After which, you need to remove all the vowels from the phrase, which leaves: b r n g m h l t h. (Some feel that using both consonants and vowels is acceptable.)
Next, you will remove any letters that are duplicated, leaving you with: b, r, n, g, m, h, l, and t.
Then, choose a letter as a single starting place and begin to combine them in different ways until you have a sigil that has all the remaining letters attached in a way that looks pleasing to your eyes. It may take several attempts to find one you think is correct for you.
Remember, you need to link all the letters together into a single unit. The letters do not have to be facing the way they normally do when written. The letters may be written reversed, diagonal, or even backward to increase the beauty of the sigil.
It is your spell, your sigil; it only needs to please you.
