Luach Eres is one of the polemic books authored by the Ya'avetz. It was written in response to the book Sha'arei Tefillah by the grammarian Rabbi Zalman Hena [the Razeh], in which he suggests many corrections to the version of prayers based on his knowledge of Hebrew grammar. In his book Luach Eres, Ya'avetz sharply criticizes the corrections of the Razeh with hundreds of polemic cutting censures on his work. the Ya'avetz even accuses the Razeh of forging the approbation of his father, the Chacham Zvi to his book. In spite of the struggle of the Ya'avetz in his opposition to the Razeh, many of the Razeh's corrections to the siddur have been accepted in our siddurim.
the author, Rabbi Ya'akov Yisrael Emden – the Ya'avetz (1798-1876), the eldest son of Rabbi Zvi Ashkenazi author of Chacham Zvi. An exceptional Torah genius, one of the greatest scholars of his times and considered one of the most prominent Achronim. He wrote dozens of compositions, most of which were printed in the printing press which he established in his home in the city of Altona. these compositions were printed in limited editions and can scarcely be found today. In spite of their rarity, his halachic compositions were reprinted in numerous editions although the many polemic books he printed were not reprinted (with the exception of limited research editions).
