Seeligman, Christian Gottlieb. Sepher MInhagim shel Yom Tov ve-Chathunoth - Juedischer Ceremonien von der Jueden Hochzeiten / Fest= und Feyer=Tagen durchs gantze Jahr [“Jewish Ceremonies of the Jewish Wedding / Feast and Fast Days throughout the year.”]

The author was a Jewish convert to Christianity who sought to portray Judaism as a superstition rather than a religion: "Christian Gottlieb Seeligman's monograph on Jewish wedding and holiday festivities was intended to provide examples of superstitious behavior, to serve as a warning to readers, who were exhorted to beseech God to protect them from error and superstition.” E. Carlebach, Divided Souls: Converts from Judaism in Germany, p. 198 and p. 300
