LEG ROT-A-
T I O N IN
HANDS-AND-
KNEES ATTI-
TUDE (End of
Second Phase).
The left leg has
reached the
maximum point
of its circular
outward move-
ment and the tip
of the toes is at
its furthest from
the floor. The
leg is pointed
straight at the
spectator and is,
therefore, much
foreshortened in
perspective.
