GRISAR, HARTMANN. - Jesuit, historian, archaeologist, and apologist, b. at Coblenz on 22 Sept. 1845, d. at Innsbruck on 25 Feb. 1932. After his early studies in Coblenz, he went to Münster, then to Innsbruck, where he attended the Jesuit boarding school, and finally to Rome at the German-Hungarian College. Ordained priest, he entered the Society of Jesus in Rome on 24 Nov. 1868. In 1870 he went to Austria and was called to the chair of ecclesiastical history in the theological faculty at Innsbruck.
At Innsbruck his fruitful activity made him one of the most diligent and valuable contributors to the *Zeitschrift für katholische Theologie*, of which he was one of the founders from 1877. Called to Rome by Cardinal Hergenröther, he then devoted himself deeply to the study of the Christian monuments of Rome, its libraries, archives, museums, and countryside. The invaluable fruit of his long research are the chronicles which, under the title *Archeologia*, he poured into *La Civiltà Cattolica* during his long Roman sojourn, which made him one of the most profound connoisseurs of ancient Rome, both classical and Christian.
To him is owed the exact topographical identification of S. Maria Antiqua, confirmed by the discovery of 1900.
Grisar deserves credit for having proved that the apostolic memoria in *Catacumbas* was located in the Basilica itself and not in the so-called *platonica* to the west of it, which was the burial place of the martyr St. Quirinus. He discovered a *privilegium* of the year 1521 relating to the Basilica of St. Sebastian, which he himself found in Umbria (*Die römische Sebastianuskirche und ihre Apostelgruft im Mittelalter*, in *Römische Quartalschrift*, 9 [1895], pp. 409-61). To him also belongs the merit—achieved amid many thorns, as is every noble human activity—of the treasure of the Sancta Sanctorum, of which he gave a remarkable illustration in two editions: *Il Sancta Sanctorum ed il suo tesoro sacro* (Rome 1907); *Die römische Kapelle Sancta Sanctorum und ihre Schatz* (Freiburg 1908).
Forced to leave Rome, his studies turned to Luther. His major work *Luther* appeared in Freiburg im Br. (1911-13; English ed. 1913-17); later, six fascicles of *Lutherstudien* (ib. 1921), then *Der deutsche Luther im Weltkrieg und in der Gegenwart* (ib. 1924); finally *Martin Luthers Leben und sein Werk* (ib. 1926, with Hungarian ed. 1929, English 1930, and French 1931; Ital. Turin 1933).
In 1924 appeared his monograph *Die Stationen und ihre Perikopen im römischen Missale. Liturgiegeschichte - die Studien aus der römischen Stadtgeschichte*, in Miscellanea Ehrle (Studi e testi, 38), II, Rome 1924, pp. 101-140. These are studies on the history of the liturgy in relation to the history of the city of Rome; a first group consists of the Masses with local elements of the Station; a second group of the Masses with hagiographical elements; the third group of Roman usages to explain the stational Mass. Then the stations of Holy Week, of the three Sundays before Lent, of the Ember Days, of Advent, of Christmas, of Easter, and of Pentecost. He later developed the same subject in *Das Missale im Lichte der römischen Stadtgeschichte* (Freiburg im Br. 1925).
His last writing is a homage to the Blessed Virgin, of whom he was always most devoted: *Marienblüten. Systematische Marienlehre aus dem grossen Marienwerk des Petrus Canisius* (ib. 1930). He wrote his autobiography in *Religionswissenschaft in Selbstdarstellungen* (ib. 1927), pp. 37-56.
