Stars’ appearance occurs on the N-E-S horizon and disappears on the S-W-N horizon. An observer located on Earth’s crust does not notice the tour the planet is achieving from West to East (which is the actual reason why we are able to notice the displacement of stars from East to West). Neither do we perceive Earth’s orbit around the Sun. Our vision is the one of Earth as the central element of the others star’s orbits. Thus, the Sun describes an apparent orbit around Earth that we call elliptical and needs one year to be fully executed. This real vision corresponds to the Geocentric model.
As Earth inhabitants and consequently the centre of reception of these occurrences, if we want to study the effects and interactions of the cosmos to understand the relations between the cycles and rhythms of “time” and those of “life” through vital and metabolic processes, we have to consider the Geocentric system.
There is in the sky a lot of stars’ groups, also called constellations but we focus especially on the “Zodiac Ring” made of a strip of constellations in front of which the Sun, stars and other planets are passing.
The three constellations corresponding to each element form a trigone and are separated by 120º angles. The Moon passes every nine days in front of a constellation of the same element. The passage of the Moon in front of each constellation varies from one to four days. During this time, the prevailing influence is the one reflected by the Moon, coming from this constellation.
The four-element’s theory goes back to the Ancient Greece. Aristotle explained in his book of Meteorology this qualitative approach of the world. He was explaining that we should base our self on the four elementary qualities: heat, cold, humidity and dry to understand the elements Earth, Water, Fire and Air. It is also necessary to distinguish the different states of matter: solid, liquid and gas.
Earth element is made of cold and dry; Water of cold and humidity; Fire of warmth and dry; Air of heat and humidity.
To understand the four elements, we must consider the Nature both from quantitative and non-quantitative points of view. Temperatures, humidity and others measurements are not sufficient to understand the deep Nature.
Earth element expresses itself in whatever is tough, dense, closed, fixed, dark. In the plant, the root has the qualities of this element. It is the vegetal organ that lasts the most, that is sometimes covered by a woody layer. It is the vegetal part from which life is expending. Earth element provides to the plant the anchoring necessary to its development.
On the contrary, Water element is of extreme mobility since aqueous substance go easily from liquid matter to solid or gas. Water never gets fixed but shapes everything. In the plant, the leaves are closely linked to this element, they adapt their self depending on the space they have, and can be of any shape, able to realise any type of metamorphosis. They never keep being the same and change significantly depending on external influences.
Fire element has a destructor character but also provide energy. Without heat, life cannot be developed on Earth surface, and without fire, life cannot regenerate. In the vegetal world, fire expresses itself in the seeds of the fruit. Seed are of extreme concentration, like mineralised, and only from there that life can appear. In the fruit, it is the solar concentration that generates the sugars and aromas accumulated.
Air element does not interact in the formation or functioning of plants, but guarantees their balance. The surrounding air may be one of the lightest and softest things existing and brings its subtlety and lightness to the fruits. Being invisible, impalpable and discreet, it allows us to perceive through our senses: colours, noises, odours… For example, in the plant, Air element transforms the vegetal leaf into a flower: a light, coloured and aromatic organ.
