Analysis of information sources in references of the Wikipedia article "Ελληνική γλώσσα" in Greek language version.
Most of the alphabets used today descended from the Phoenician one. The Greeks adopted it about 2,800 years ago, modifying the characters to suit sounds in their own language.
... the Greek alphabet has served the Greek language well for some 2,800 years since its introduction into Greece in the tenth or ninth century BC.
The element that makes this text a unicum is that it is written in Greek script. In the Ottoman Empire, the primary criterion for the selection of an alphabet in which to write was religion. Thus, people who did not speak—or even know—the official language of their religion used to write their religious texts in the languages that they knew, though in the alphabet where the sacred texts of that religion were written. Thus, the Grecophone Catholics of Chios wrote using the Latin alphabet, but in the Greek language (frangochiotika); the Turcophone Orthodox Christians of Cappadocia wrote their Turkish texts using the Greek alphabet (karamanlidika); and the Grecophone Muslims of the Greek peninsula wrote in Greek language using the Arabic alphabet (tourkogianniotika, tourkokretika). Our case is much stranger, since it is a quite early example for that kind of literature and because it is largely concerned with religious themes."; p. 306. The audience for the Greek Mi'rājnāma was most certainly Greek-speaking Muslims, in particular the so-called Tourkogianniotes (literally, the Turks of Jannina). Although few examples have been discovered as yet, it seems that these people developed a religious literature mainly composed in verse form. This literary form constituted the mainstream of Greek Aljamiado literature from the middle of the seventeenth century until the population exchange between Greece and Turkey in 1923. Tourkogianniotes were probably of Christian origin and were Islamized sometime during the seventeenth century. They did not speak any language other than Greek. Thus, even their frequency in attending mosque services did not provide them with the necessary knowledge about their faith. Given their low level of literacy, one important way that they could learn about their faith was to listen to religiously edifying texts such as the Greek Mi'rājnāma.
