Chaldea is the southwest most portion of Mesopotamia, also known as Sumeria, and its capitol city was Ur.
It is considered to be the cradle of Western civilization, dating back over 10,000 years.
All the sciences having originated from there, spread in a westward direction.
They were a distinctive group of people, with no relation in ethnicity, language or culture to any other known civilization. The Chaldean tradition states that their origin was not human, but Divine. And that their task was to spread Divine knowledge to all mankind. They considered their sacred knowledge as universal, and timeless.
In Chaldea, all areas of life were inseparably linked with Numerology, the science of numbers. Not only at a mathematical level, but metaphysical as well.
According to the 'Chaldean Book of Numbers', numbers represent the energies of creation. Energies that are perpetually in motion, responding to the divine order of the universe.
The energetic representation of the numerical digits are considered to correspond to the planets or heavenly bodies, and more important still, to the basic primordial energies from where creation sprang forth.
From this basic principle, Numerology was used as an integrated system of identifying and timing the works of nature, the life and events of individuals and collective societies.
However, it should be noted, that the number Zero is not part of the Chaldean schema of Numerology. Zero was used later by the Arabs, strictly for mathematical purposes, but not for Numerology.
Chaldean Numerology is always performed in synergy with Chaldean Astrology, and are inseparable. Numerological analysis always precedes that of the Natal Chart, both sharing the same objectives. Chaldean astrology is based on the Sidereal Zodiac and the Equal house system. Its predictive methods are primarily based on the Luminary Planets: the Sun and Moon.
In the Sidereal Zodiac, the Vernal Equinox which used to occur in the constellation of Aries now occurs in the constellation of Pisces, due to the Precession of the Equinoxes, of about 23 degrees. This is different from the Tropical Zodiac, which identifies the commencement of the Vernal Equinox to be the beginning of the Sun's entrance into the sign of Aries.
In the Equal House System, each house is identical to the 30 degrees of each sign. All signs are associated with only one house. In other words, you'll never find a sign that spans between two houses.
For the Chaldeans, spirituality, numerology, astrology and medicine were not isolated branches of knowledge, but were all intertwined.
The Chaldeans considered their sciences to be of Divine origin. They regarded that all their knowledge came from a source, back in antiquity, from which all mankind drew their knowledge. As divisions among men multiplied, this original knowledge, spread and was described in the languages and cultures of different groups of men. At a certain point in time, a great deluge removed many of these inhabitants from the face of the earth, erasing forever any traces as to their existence.
Chaldean writings reflect that asceticism was a key element in life, and they believed that undue involvement with this world was a cause of mans suffering and pain. They consider that mans highest duty is to rise above the body, the emotions, the mind, and unite his soul with the 'Eternal One'.
The Chaldeans believed in one Supreme God, who had 3 main archangels, who in turn had a hierarchy of angels who discharged specific functions in creation. Originally, they did not have a fixed name for them, as they considered them of spiritual essence, untainted by material description. In addition, they considered that the 'Breath of Life' played a vital role in mans process of spiritual transcendence.
It is a historical fact, that Abraham, the father of both the Israelites and Arabs, was from Chaldea (city of Ur), and that Numerology permeated both the Kabbalah and Sufi mystic traditions.
The Greeks in particular, benefited from the Chaldeans. Prominent scholars such as Pythagoras, Ptolemy, and Hippocrates diligently studied Chaldean spirituality, numerology, astrology, and medicine respectively, translating the information into Greek. The Romans in turn, learned from the Greeks, and Europe from the Andalusian Caliphate in southern Spain, giving rise to the renaissance period of classical learning.
The Arabs in the Middle East continued to preserve and build upon the Chaldean sciences, making discoveries and innovations of their own.
The influences Chaldean sciences exerted were many, and it constitutes the basis, from which western sciences evolved from.
