Aleister Crowley's Lam & the Little Grey Men - was the Amalantrah working humanity's first contact with aliens?

In January through March of 1918 Crowley began a series of magickal workings called the Amalantrah Workings in furnished rooms in Central Park West, New York City. These were a performed via Sexual & Ceremonial Magick (his spelling) with the intent to invoke certain "intelligences" to physical manifestation.

In actuality, the workings typically manifested as a series of visions and communications received through the mediumship of his partner, Roddie Minor.

Be that as it may, at least one such "intelligence" was brought into physical manifestation via the Magickal Portal they created. (A portal in this context is a "magickally" created rent in the fabric of time and space.) The entity that came through is the one pictured above left. Crowley maintained the picture is actually a portrait and drawn from real life. This entity either called itself "Lam," or was named "Lam" by Crowley. Either way, he considered it to be of interdimensional origin, which was the term then for extraterrestrial. In communications with Lam, the symbolism of the egg featured prominently.

Crowley included the portrait of Lam in his Dead Souls exhibition held in Greenwich Village, New York, in 1919.
