In Mecklemburg (Germany), Saint John the Irish, bishop & martyr (1066).
An Irish monk, John was consecrated a bishop and undertook missionary
journeys, first to Iceland, in the middle of the 11th century, then to
Germany, where Saint Adalbert, archbishop of Hamburg, gave him the new
diocese of Mecklemburg with the mission of converting the whole region.
John met a martyr's end in the same year as the prince of the Obotrites,
Gotescalc, who had given himself as a champion of the Gospel (1066). As
with Gotescalc, John the Irish is present in the canon of the Saints but
without having had any cult.. - Acta sanct., 10 November, t. 4, p.
564-566. - Cf. 7 june, t. 6, p. 132-133.
