Maritxu (María) Erlantz Guller (Isaba, Navarre 1912[1] – San Sebastian, 1993[2]), also known as the "sorgin ona" or white witch of Ulia, was a teacher, tarot reader and fortune teller who supposedly had paranormal powers.[3]
Maritxu studied to become a teacher in Pamplona and subsequently worked as a teacher in Irañeta during the Spanish Civil War.[4] [5] On 8 October 1938 she married a Swiss man named Giovanni Guller, who encouraged her to deepen her studies in parapsychology.[6] The couple moved to San Sebastian in 1952 and settled in a baserri in Mount Ulia.[1]
Maritxu created various Tarot decks which were published by Fournier including El Gran Tarot Esoterico in 1976 (with illustrations by Luis Pena Longa) along with its instruction manual.[7] [8] [9] This deck features classic Tarot motifs as well as variations inspired by French astrologer and tarot reader Eudes Picard. 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) and the Tarot de Euskal Herria in 1991 (with illustrations by Alfredo Fermín Cemillán "Mintxo"), which she dedicated "to all women, to help them interpret the Tarot wisely."[10]
In addition to her Tarot decks, Maritxu created over 36,000 grimoires for divination.
A children's park is named after her in San Sebastian, where she lived for many years.[11]
