Landgraviate of Hesse-Darmstadt
In 1685, Schotten HaCohen was appointed dean of the zur Klause yeshiva in Frankfurt and Rabbi of the Landgraviate of Hesse-Darmstadt. For two years starting 1703, when there was no chief rabbi of Frankfurt, he served as acting head rabbi of the city. During the laying of the foundation stone for the new synagogue following the fire that had ravaged Frankfurt's Jewish ghetto in 1711, Schotten HaCohen recited prayers he had composed in Hebrew. In 1715, he instructed community members to wear simple dress and limit their spending on festivals.t
