Were both Giuseppe Ungaretti and Aleister Crowley a poet?
yes
Aleister Crowley
Aleister Crowley ( ; born Edward Alexander Crowley; 12 October 1875 – 1 December 1947) was an English occultist, ceremonial magician, poet, painter, novelist, and mountaineer.
 He founded the religion of Thelema, identifying himself as the prophet entrusted with guiding humanity into the Æon of Horus in the early 20th century.
 A prolific writer, he published widely over the course of his life.
Giuseppe Ungaretti
Giuseppe Ungaretti (] ; 8 February 1888 – 2 June 1970) was an Italian modernist poet, journalist, essayist, critic, academic, and recipient of the inaugural 1970 Neustadt International Prize for Literature.
 A leading representative of the experimental trend known as "Ermetismo" ("Hermeticism"), he was one of the most prominent contributors to 20th century Italian literature.
 Influenced by symbolism, he was briefly aligned with futurism.
 Like many futurists, he took an irredentist position during World War I. Ungaretti debuted as a poet while fighting in the trenches, publishing one of his best-known pieces, "L'allegria" ("The Joy").
Libri of Aleister Crowley
The Libri of Aleister Crowley is a list of texts mostly written or adapted by Aleister Crowley.
 Some are attributed to other authors.
 The list was intended for students of Crowley's magical order, the A∴A∴. Collected Works of Aleister Crowley 1905-1907
The Collected Works of Aleister Crowley 1905–1907 was originally a trilogy of books published by Aleister Crowley during his early career as student of magick. Liber OZ
"Liber OZ" (or "Book 77") is a single page by English author and occultist Aleister Crowley purporting to declare mankind's basic and intrinsic rights according to Crowley's philosophy of Thelema.
 Written in 1941 (though based on a much earlier O.T.O. initiation lecture), the work consists of five succinct and concise paragraphs, being one of the last and shortest of Crowley's many "libri," or books. Rites of Eleusis
The Rites of Eleusis were a series of seven public invocations or rites written by British occultist Aleister Crowley, each centered on one of the seven classical planets of antiquity.
 They were dramatically performed by Aleister Crowley, Leila Waddell (Laylah), and Victor Benjamin Neuburg in October and November, 1910, at Caxton Hall, London.
 This act brought Crowley's occult organization the A∴A∴ into the public eye. L'allegria
L'allegria (Joy/Happiness or better, Merriness) is a collection of poems published by Giuseppe Ungaretti in 1931.
 It was an expanded version of a 1919 collection "Allegria di naufragi" (merriness of the castaways).
 Many of the poems were written in reaction to Ungaretti's experience as a soldier of World War I. The Magical Revival
The Magical Revival is a book written by British occultist Kenneth Grant, first published in 1972.
 It is the first of his "Typhonian Trilogy", which comprises this work and two others—"Aleister Crowley and the Hidden God" (1973) and "Cults of the Shadow" (1975).
 In this work, he first introduced his theory that American horror author H. P. Lovecraft's Cthulhu mythos was psychic revelation presented as fiction, an idea which he would elaborate and extend further in his later works.
 This idea - that what is ostensibly presented as fiction is often a vehicle masking deeper realities - has precedence in the inclusion by Aleister Crowley of many works of fiction in the official reading syllabus of his mystical and magical order, the Argentum Astrum ; Grant's recognition of Lovecraft's value may be seen as simply a detailed continuation, an "updating" of this basic idea using material which Crowley simply hadn't had the opportunity to read.
 Grant also claimed in this work that there was an unconscious connection between Lovecraft and occultist Aleister Crowley, arguing that both of them channeled their work from the same occult forces, although Lovecraft was not consciously aware of the alleged otherworldly sources of his literary inspirations. Richard Kaczynski
Richard Kaczynski is an American writer and lecturer in the fields of social psychology, metaphysical beliefs and new religious movements.
 He is known for his biography of the occultist Aleister Crowley, "Perdurabo: The Life of Aleister Crowley", described by "The Times Literary Supplement" as "the major biography to date", and by the Norwegian daily "Aftenposten" as the best biography of Crowley. The Confessions of Aleister Crowley
The Confessions of Aleister Crowley : An Autohagiography, by Aleister Crowley (1875–1947), is a partial autobiography by poet and occultist Crowley.
 It covers the early years of his life up until the mid-late 1920s but does not include the latter part of Crowley's life and career between then and his death in 1947.
