Ancient Jewish letters are very characteristic of Castel’s work from the 1950’s. Influenced by his father- a Hebrew calligrapher, he transformed the ancient letters to undecipherable signs. This he did in a unique technique using Basalt and vivid colors. The physical element (basalt) and the spiritual (ancient letters) connect Castel to the roots of the Jewish people living in their land.
Castel was born in Jerusalem in 1909. He studied in Betzalel and spent 10 years studying in Paris between 1925-1935
