April is, as surely well known, entirely devoted to Venus. This Goddess is linked to Love, a concept which, of course, has not to be intended in a profane sense.
Love linked to the Divine energy of Venus must be considered as Prime Cause, as a force placed at the origin of the matter and the organization of Life. Love/Venus is also the origin of pure feelings.
Love is a Force pushing towards Beauty, in particular the "Hidden Beauty" (occultum formosum) of which the perceivable beauty is only the most superficial aspect.
The Green Path, the "Hidden Beauty", Water, Life, First Cause, The Origin of Everything; the meanings and the symbolic value of Love (as a Force tending to Life) are extremely complex. However all this can be useful to understand why Rome, both as material and immaterial space) has been founded in this particular period of the sacred year and why Rome (and its name) are connected to Venus.
