In astronomy the axis mundi is the Latin term for the axis of Earth between the celestial poles.
In ancient Greco-Roman astronomy, the axis mundi is the axis of rotation of the planetary spheres within the classical geocentric model of the cosmos.
In 20th-century comparative mythology, axis mundi is also called the cosmic axis, world axis, world pillar, center of the world, or world tree — has been used to refer to any mythological concept of "the connection between Heaven and Earth" or the "higher and lower realms."
"By these three days all the world is called to attention. Everything that is and ever was and ever will be , the macro and the micro, the galaxies beyond number and the microbes beyond notice - everything is mysteriously entangled with what happens in these days. This is the axis mundi, the center upon which the cosmos turns. In the derelict who crys from the cross is, or so Christians say, the Alpha and the Omega, the beginning and the end. The life of all on this day died. Stay a while with that dying." Death on a Friday Afternoon by Richard John Neuhaus, page 2.
