Caroline Walker, The Modern Dances — Chapter IV. The Castle Walk (1914)
“ The Castle Walk Originated and made famous by Mr. and Mrs. Vernon Castle, the Castle Walk has become immensely popular through its introduction into the Tango. It really is so simple that it is difficult to describe. In this figure the man continually goes forward and the lady backward. In order that the lady may be properly guided about the room, the man's arm encircles her just under her arm, while her left hand rests on the man's right arm. The position of the lady's right arm and the man's left arm is high, with their hands clasped. ”
