Shimeon Kippah known to some as פטר חמור was the last leader of the Galilean Sanhedrin and later a Stylite around 426CE.. The Machzor Vitri p. 282 Mahadurah Makitzei Nirdamim says
- “Some say Nishmas was authored by the Abomination of Rome(!) called Shimon Peter Chamor (who authored this liturgy and others while in the cave) Vechas Veshalom to say such a thing, and one who says so will have to bring a fat offering when Moshiach comes”
Vetzaruch Iyun (צריך עיון), as elsewhere in Machzor Vitri it states that Shimon Kipa authored the Piyutim of Seder Avoda said on Yom Kippur.
Siddur Avodas Yisrael, in name of an old manuscript siddur from the year 1407
- “I heard from Yehuda Bar Yaakov that Shimon Ben Kipa authored Nishmas until the words Mi Yidmeh Lach”
