"In the Timaeus, Plato's major cosmological dialogue, the Platonic solid he associated with fire was the tetrahedron which is formed from four triangles and contains the least volume with the greatest surface area. This also makes fire the element with the smallest number of sides, and Plato regarded it as appropriate for the heat of fire, which he felt is sharp and stabbing, (like one of the points of a tetrahedron)".
The couple is on fire, then, with passion 4 life, fo(u)r each other, and new experiences.
Fire is an extrovert and energetic element, corresponding to the South (You chose the South of Greece as the starting point of their journey), while its archetype is that of the Warrior.
These two warriors of life are still contributing to each other's widening. And they still have Athena by their side.
It is going to be an interesting journey within their journey, then. And we will travel with them through your beautiful narrations, Patrick.
