WHY CROSSES ?
The Arlington West's, and North's, East's, and South's use the ancient pre-Christian symbol of a cross for economic reasons, as well as storage ability. We certainly know and of course acknowledge that those thousands who were killed, were not just Christians, but women and men who embraced the full spectrum of faiths and no faiths. So the symbols of crescents for Arabs, Star of David for Jews, or symbols for the panoply of faiths cannot detract from the real reason and symbol DEATH.
From its simplicity of form, the cross has been used both as a religious symbol and as an ornament, from the dawn of man's civilization. Various objects, dating from periods long anterior to the Christian era, have been found, marked with crosses of different designs, in almost every part of the old world. India, Syria, Persia and Egypt have all yielded numberless examples, while numerous instances, dating from the later Stone Age to Christian times, have been found in nearly every part of Europe. The use of the cross as a religious symbol in pre-Christian times, and among non-Christian peoples, may probably be regarded as almost universal, and in very many cases it was connected with some form of nature worship.
