There being, then, in "religion" a strong sensual element, ingenuity has been exercised to a wonderful extent in the contrivance of designs, nearly or remotely significant of this idea, or rather union of the conceptions to which we have referred. Jupiter is a Proteus in form; now a man, now a bull, now a swan, now an androgyne. Juno, or her equivalent, is sometimes a woman, occasionally a lioness, and at times a cow. All conceivable attributes of man and woman were symbolised; and gods were called by the names of power, love, anger, desire, revenge, fortune, etc. Everything in creation that resembled in any way the presumed Creator, whether in name, in character, or in shape, was supposed to represent the deity. Hence a palm tree was a religious emblem, because it is long, erect, and round; an oak, for it is hard and firm; a fig-tree, because its leaves resemble the male triad. The ivy was sacred from a similar cause. A myrtle was also a type, but of the female, because its leaf is a close representation of the vesica piscis. Everything, indeed, which in any way resembles the characteristic organs of man and woman, became symbolic of the one or the other deity, Jupiter or Juno, Jehovah or Astarte, the Father or the Virgin. Sometimes, but very rarely, the parts in question were depicted au naturel, and the means by which creation is effected became the mundane emblem of the Almighty; and two huge phalli were seen before a temple, as we now see towers or spires before our churches, and minarets before mosques. (Lucian, Dea Syria.) Generally, however, it was considered the most correct plan to represent the organs by some conventional form, understood by the initiated, but not by the unlearned. Whatever was upright, and longer than broad, became symbolic of the father; whilst that which was hollow, cavernous, oval, or circular, symbolised the mother. A sword, spear, arrow, dart, battering ram, spade, ship's prow, anything indeed intended to pierce into something else was emblematic of the male; whilst the female was symbolised as a door, a hole, a sheath, a target, a shield, a field, anything indeed which was to be entered. The Hebrew names sufficiently indicate the plan upon which the sexes were distinguished; the one is a zachar, a perforator or digger, and the other nekebah, a hole or trench, i, e. male and female. These symbols were not necessarily those of religious belief. They might indicate war, heroism, prowess, royalty, command, etc., or be nothing more than they really were. They only symbolised the Creator when they were adopted into religion. Again, there was a still farther refinement; and advantage was taken of the fact, that one symbol was tripliform, the other single; one of one shape, and the other different. Consequently, a triangle, or three things, arranged so that one should stand above the two, became emblematic of the Father, whilst an unit symbolised the Mother.
