Maritxu Güller

Maritxu (María) Erlantz Guller (1912–1993), also known as the "sorgin ona" or "white witch of Ulia", was a Spanish teacher, tarot reader and fortune teller who supposedly had paranormal powers.

Life Maritxu was born in 1912 in Isaba, Navarre. She studied to become a teacher in Pamplona and subsequently worked as a teacher in Irañeta during the Spanish Civil War. On 8 October 1938 she married a Swiss man named Giovanni Guller, who encouraged her to deepen her studies in parapsychology. Designed by Maritxu and illustrated by Luis Pena Longa, the deck features classic Tarot motifs as well as variations inspired by the system of French astrologer and tarot reader Eudes Picard, first outlined in his 1901 work. The deck was republished in 2016 by Lo Scarabeo and distributed by Llewellyn Worldwide. Martitxu also created two Basque themed decks; the Euskal Tarot Mitika or Basque Mythical Tarot in 1982 (with illustrations by Angel Elvira which were inspired by Basque mythology)

In addition to her Tarot decks, Maritxu created over 36,000 grimoires for divination. A children's park is named after her in San Sebastián, where she lived for many years.
