Mateus Maria100pxMaria J. Mateus, has a BA in psychology from the University of Texas and MA in astrology from Kepler College.

Maria believes the key to understanding all of astrology, is to understand the manner in which language and mind reflect the world we live in. In 2002, her desire to demystify the relationship between inner emotional states and outer world manifestations led her to embark on an investigation that culminated in the development of the LINCOS grammatical approach to astrology.

Maria has been a student of astrology since she was a teen. She's open to all astrological schools, but maintains  a particular interest in research, history, language, and ancient techniques.

Maria has lectured at conferences and workshops around the world and taught at the International Academy of Astrology and Kepler College. She's written for several astrological publications, translated a modern introduction to traditional techniques (On The Heavenly Spheres), and is currently translating its sequel, as well as working on her own work on grammatical astrology.
