English terms with diacritical marks
The Old English Latin alphabet began to replace the Runic alphabet in the 9th century, due to the influence of Celtic Christian missionaries to the Anglo-Saxon kingdoms. The orthography of Old English – which was entirely handwritten in its own time – was not well standardized, though it did not use all the Latin letters, and included several letters not present in the modern alphabet. When reprinted (on a printing press or computer) in modern times, an overdot is occasionally used with two Latin letters to differentiate sounds for the reader:
English Qabalah
In one of the Holy Books of Thelema written by Aleister Crowley in 1907, called "Liber Trigrammaton, sub figura XXVII -- Being the Book of the Mutations of the Tao with the Yin and the Yang" are 27 three-line diagrams known as 'trigrams', which are composed of a solid line for the Yang, a broken line for the Yin, and a point for the Tao. By attributing 26 Roman script letters to the trigrams of this work, Crowley felt that he had fulfilled the injunction to "obtain the order & value of the English Alphabet", as noted in his 'Old Comment' to The Book of the Law. Crowley did not go on to develop a full qabalah from this work, but many subsequent qabalists have been inspired by the injunction in verse 2:55 to develop a more complete system of English Qabalah, using various methods of exegesis.
