The first six lines are identical (so near as not to quibble) to a magical incantation used to summon a magical horse found in a Slavic folktale published in the 19th century, called "The History Of Prince Slugobyl; Or, The Invisible Knight"
“Magu (sic), Horse with Golden Mane,
I want your help yet once again,
Walk not the earth but fly through space
As lightnings flash or thunders race.
Swift as the arrow from the bow,
Come quick, yet so that none can know.”

Just found this reading folktales last night :-D Since Brock wrote this one, I'm guessing Moorcock ain't the only one who riffed off folktales
