Escuela Magnetico-Espiritual de la Comuna Universal

In 1912, Mateo traveled to East Jerusalem, where he was received by the guardians of the school of the Essenes Kábala; he received the order to open a school, intended as a continuation of the Kábala. The new school he founded, Escuela Magnetico-Espiritual de la Comuna Universal (EMECU), became popular. In its first twenty-four years, 184 branches opened in several Spanish provinces, as well as Cuba, El Salvador, the United States (US), Guatemala, Honduras, Mexico, Nicaragua, Puerto Rico, Santo Domingo, Uruguay and Venezuela.^[4] For administrative operations, the schools established a rigid discipline, governed by a document entitled, "Rules of Procedure, Statutes, Circulars and Articles", from its official magazine, La Balanza ("The Balance"). The document describes a "personality", whereby the Civil School is an educational institution for philanthropic and cultural studies, with own metaphysical and scientific methods.

Unity for Spanish speakers

In addition to writing on spiritism, Mateo promoted the progress and unity of Spanish-speaking people. On October 12, 1921, he developed the Hispanic-American-Oceanic Union (UHAO), symbolized by a flag with the seven colors of the rainbow and the Basque Oak tree of Guernica. In 1925, he founded the Organization Templo Azul Racionalista (Otar), for scientists and intellectuals, and then the "Circle Master's Advocate", a secular education program, whereby teachers would instruct other teachers.

Nicaraguan revolutionary and politician, Augusto César Sandino, was one of the best-known followers of Mateo's "Luz y Verdad" ("Light and Truth") manifesto of 1931.

The Colony Jaime (Santiago del Estero)

On July 25, 1931, Mateo directed the founding of Colony Jaime (607 hectares (65,300,000 sq ft)), located in Robles in the northern province of Santiago del Estero, Argentina; the Colony remained in existence as of 2012. In 2012, twenty-five families, consisting of seventy-nine children, teenagers and adults, are the Colony's residents.^[5][6] It is located near the city of Santiago del Estero (capital of the province).

Since 1952, Colony Jaime collaborates with the Cologne Provincial Public School No. 667 Pedro Juricich (primary and secondary EGB3 initial level), which works with many children from the area who attend the association.

Mateo also created the Colonia Los Libertadores.

Death and administration

At the time of Mateo's death on December 6, 1935, it was revealed that he had left directorship duties of the school to his wife, Maria Mercedes Riglos Cosis. She delegated this authority to their eldest son, Juan Trincado Donato, who died in 1992.
