USAGE OF THE SWASTIKA IN CHRISTIAN CONTEXT
The primitive form of the cross seems to have been that of the so-called "gamma" cross (crux gammata), better known to Orientalists and students of prehistoric archaeology by its Sanskrit name, swastika...There are other forms of cross, such as the crux gammata, the crux Florida, or flowering cross, the pectoral cross, and the patriarchal cross. But these are noteworthy rather for their various uses in art and liturgy than for any peculiarity of style...Another symbol largely employed during the third and fourth centuries, the swastika already spoken of at some length, still more closely resembles the cross. On monuments dating within the Christian Era it is known as the crux gammata, because it is made by joining four gammas at their bases.
