Today, 374 years ago, in the year 1646, the Shach started printing his sefer Sifsei Cohen a.k.a. Shach.
Rabbi Shabsai Cohen, famously known as the Shach, which is the acronym of his sefer, Sifsei Cohen.
The first sefer was on Shulchan Aruch Yoreh Deah. For this he travelled to Cracow, and commissioned his wife’s relative, R’ Nachum Meisels, who had a printhouse, to print his work. For the sefer, they used a special font called Venetzia, which was a copy from the font used by the venetian printhouses.
