In page Adalbert of Prague:

"

After spending a year on the Aventine, Adalbert set out on a pilgrimage through France and Germany in June 996.[4] Between September and November, he stayed at the court of Emperor Otto III.[4] During this time, he was released from his duties as bishop of Prague and was free to devote himself to the Christianization of pagan lands as a missionary bishop. From the imperial court, he traveled to a place referred to in the sources as Mestris, which Gerard Labuda identifies as Pécsvárad (Mons Ferreus) in Hungary.[4] He probably baptized there Géza of Hungary and his son Stephen in Esztergom[citation needed]. From there, in March 997, he went to the court of the Polish duke Bolesław Chrobry in Gniezno.[4]
