Zick received early instruction from his father, the painter Johann Zick, who was an exponent of the rococo "Rembrandt manner" in the easel painting, but in fresco painting follow the tradition of Asam and Bermüller. In 1757 Zick went to Rome to complete his training under Mengs. Nevertheless, he remained true to the Bavarian rococo manner even though some classical elements into it into his work. His first important commission was the declaration on the Warteau room in Schloss Bruchsal Palace (1759), and his greatest work is the fresco in the library of Schussenried Monastery or perhaps the frescoes in the church of Wiblingen Monastery (1778 -- 1780). Zick also produced fine panel paintings, etchings and architectural designs. His work is representative of the critical transition period leading from the rococo neoclassicism.
