She appeared in the costume of Isis

According to Bakst.

It was four of the clock ere I quitted

These scenes of eclectic delight;

The fogies had most of them flitted,

The revels were still at their height;

For Garvin was dancing a Tango,

His head in the place of his legs;

And Spender a blameless fandango

Encircled by eggs.
