In this paper, the relation between the Steiner vector of a one-parame
ter closed spherical motion and the area vector of the closed spherica
l curve formed under the motion is discussed and some corollaries are
given. Moreover, making use of the area formula of W. Blaschke and the
area vector defined by H. R. Muller, the formula given by H. H. Hacis
alihoglu is obtained by a different method.
