Today, 545 years ago, in the year 1475, the first version of the Tur/Arba’ah Turim, was finished.
“And the holy work was finished, Monday 28 of the month of Tamuz. This is the fourth month, 5235 to the fixed number. In Piove di Sacco [a town in Italy not far from Padua], in the [print]house of R’ Meshulam called Kozi, may he be blessed from now and forever.”
This version is quite rare. The Chida, mentions in his sefer Shem Hagedolim (Sefarim, Gimel 2), having seen this edition.
