Pere Renom

“We have given you, O Adam, no visage proper to yourself, nor endowment properly your own, in order that whatever place, whatever form, whatever gifts you may, with premeditation, select, these same you may have and possess through your own judgement and decision […] We have made you a creature neither of heaven nor of earth, neither mortal nor immortal as the free and proud shaper of your own being, fashion yourself in the form you may prefer.”

Giovanni Pico della Mirandola

Lithium, a strategic element

The Catalan Chestnut Party and the Christian All Saints’ Day, the Halloween of the Anglo-Saxons, the Sanheim of the Celts, and the Roman Pomona festival are the same celebration with different appearance.
