[2] Wiliesind's name is Gothic in origin, although the diocese of Pamplona was predominantly Basque at the time.
[4] The letter survives and is an important record of the monasteries of the diocese of Pamplona and their libraries during the mid-ninth century.
[5] The letter was carried to Wiliesind by Galindo Enneconis (Íñiguez), probably a son of Íñigo Arista, the king of Pamplona, who died on 9 July 851.
If this identification is correct, then Galindo was probably returning to Pamplona because of his father's death when he was asked to carry with him Eulogius' letter for the bishop.
[6] According to a document dated to 867, a bishop of Pamplona named Gulgesind, probably the same person as Wiliesind, co-founded the monastery of Santa María de Fuenfría (Fontfrida) at Salvatierra de Esca with King García Íñiguez and Abbot Fortún of Leire.
