While thinking about mixing foxtrot and maxixe…
The St. Denis Spiral is a minor foxtrot variation from Edna Stuart Lee's Thirty Fox Trot Steps (New York, 1916) which, like the sequences in my previous post, incorporates maxixe styling in the two-step. Like Lee's Pavlowa Extension, it is named for a famous dancer, in this case Ruth St. Denis. I am not a scholar of modern dance (theatrical or otherwise), so I have only the most superficial knowledge of her career, but apparently she was indeed noted for incorporating spiral figures, as may be seen in "The Delirium of Senses" from Radha (1906), recorded at Jacob's Pillow in 1941. I seriously doubt she had anything to do with this foxtrot variation, however; the name is most likely just an homage.
The sequence is just as easy as the other foxtrot-maxixe combinations:
