Ribon Kol Ha-Olamim is a teḥinah (supplication) for entering the Shabbat that can be found in many siddurim following after the custom of the school of Rabbi Yitsḥak Luria. In his Ha-Siddur Ha-Shalem, Paltiel (Philip) Birnbaum includes it, commenting as follows: “Ribon kol Ha’Olamim is attributed to Rabbi Joseph of Rashkow, Posen, who lived towards the end of the eighteenth century. The adjectives in the first paragraph are in alphabetic order.” This can’t be correct however as a copy of Ribon Kol Ha-Olamim can be seen in the siddur Tikunei Shabbat from 1614 (see below for source images). Google Books attributes Tikunei Shabbat to Rabbi Yitsḥak Luria (1534-1572), which is the attribution we have followed, although as a posthumously published work we wonder whether it might be more properly attributed to “the School of Rabbi Isaac Luria.” Please comment below if you know of another attribution. The English translation is that of Paltiel (Philip) Birnbaum, with some minor changes that I have made to divine names and appelations.– Aharon Varady
