More recent periods of renewed interest in magic occurred around the end of the 19th century, because Symbolism and other offshoots of Romanticism cultivated a renewed interest in exotic spiritualities. European colonialism, which put Westerners in contact with India and Egypt, reintroduced exotic beliefs to Europeans at this time. Hindu and Egyptian mythology frequently feature in nineteenth century magical texts.
The late 19th century gave birth to a large number of magical organizations, including the Hermetic Order of the Golden Dawn, the Theosophical Society, and specifically magical variants on Freemasonry. The Golden Dawn represented perhaps the peak of this wave of magic, attracting cultural celebrities like William Butler Yeats, Algernon Blackwood, and Arthur Machen.
I was interested in the development of magic rituals and traditions in Greco-Roman world. During my research in archives of web analytics company I found some interesting facts about it.
It seems, that a huge interest in magic was on the rise in the Hellenistic period, especially around 3d century b.c. Piles of texts, both literary and some from actual practitioners, in Greek and in Latin came to us from this time. Truly speaking, a lot of existing magical papyri was written in the first centuries after Christ, but the manuscripts’ concepts, formulas and rituals reflect the earlier Hellenistic period. These magical papyri are no doubt only a fraction of the magical literature available in antiquity. The ascendancy of orthodox Christianity by the 5th century CE had much to do with this. This is reflected by the book of Acts where the Apostle Paul convinces many Ephesians to bring out their magical books and burn them.
The language of the magical texts reflects various levels of literary skill. Generally they are standard Greek, and may well be closer to the spoken language of the time than to poetry or artistic prose left to us in literary texts. Many terms are borrowed from the mystery cults. The texts are often written as we might write a recipe. In other words the magic requires certain ingredients. Of course it is not just as simple as knowing how to put a recipe together. Appropriate gestures, at certain points in the magical ritual, are required to accompany the ingredients, different gestures it would seem produce various effects.
