As Inman says, "Moderns who have not been initiated in the sacred mysteries and only know the emblems considered sacred, have need of both anatomical knowledge and physiological lore ere they can see the meaning of many signs." The emblems or symbols then, to which I shall particularly allude, are the _Cross_, the _Tree_ and _Grove_, the _Fish_, the _Dove_, and the _Serpent_. And first of all the Cross, about which very erroneous notions prevail. It is seen everywhere either as a matter of personal or church adornment, or as an architectural feature, and everywhere the impression prevails that it is exclusively a Christian symbol. This, however, is the grossest of errors, for the world abounds in cruciform symbols and monuments which existed long before Christianity was thought of. It is otherwise however with the Crucifix which is, of course, an absolutely Christian symbol. The image of a dead man stretched out upon the Cross is a purely Christian addition to a purely pagan emblem, though some of the old Hindoo crosses remind one of it very powerfully. No matter upon which continent we look we see everywhere the same cruciform sign among peoples and races most distinct. There perhaps has never been so universal a symbol, with the exception of the serpent. Moreover the cross is a sort of international feature, and is spoken of in its modifications as St. Andrew's, St. George's, the Maltese, the Greek, the Latin, etc. Probably because of its extreme simplicity the ages have brought but little change in its shape, and the bauble of the jeweller of to-day is practically the same sign that the ancient Egyptian painted upon the mummy cloth of his sacred dead. Thus it will appear that the shadow of the Cross was cast far back into the night of ages. The Druids consecrated their sacred oak by cutting it into the shape of a cross, and when the natural shape of the tree was not sufficient it was pieced out as the case required. When the Spaniards invaded this continent they were overcome with surprise at finding the sign of the Cross everywhere in common use. It was by the community of this emblem between the two peoples that the Spaniards enjoyed a less war-like reception than would otherwise have been accorded to them.
