Collection of five books by R. David HaKohen of Vilna, author of Ir David – printed in Jerusalem, in the 1880s.

R. David HaKohen, author of Ir David, lived in Jerusalem and printed several books in the 1870s-1880s composed of sentences which all have the numerical value of the year.

The books' purpose is clarified in the approbation of R. Yechiel Michel Pines to the 1886 part of Sukat David (not in the present volumes). Sick and unable to work, the author would make a living from his book with chronograms for the current year, which he was able to produce effortlessly.
