Johannes Laurentius Weiss (religious name Liberat) and his two companions Michele Pio Fasoli and Antonio Francesco Marzorati (religious name Samuele) were German and Italian priests of the Order of Friars Minor. All of them were missionaries. In 1704 they set off from Rome for Cairo to begin their travel through the Nile River to reach Ethiopia. But the team experienced significant pitfalls: conflicts in Ethiopia slowed them down and forced their return to Cairo though the team succeeded in their second attempt to reach their destination. Finally, anti-religious sentiment started fermenting there under the new monarch who decreed missionaries to be nothing more than heretics, which resulted in the three friars being stoned.
