Over the past three thousand years since Qin Dynasty, what was the two historical periods when the Chinese art of seals and seal engraving developed the most? As seal engraving enjoyed great development in the Ming and Qing Dynasties, who were the leading artists of this period and how did they contribute to the development of the art? What skills and cultural backgrounds are required to become a seal engraver? What are some of the valuable experience and anecdotes shared by those master engravers? Answers to these questions can be found in China in Seals, the latest book by famous engraver, calligrapher and Chinese painter Han Tianheng. Divided into three sections: "the history of seals and engraving", "concept and practice", and "famous engravers and their anecdotes", the book is an excellent reflection of Han's research in the art of Chinese seals and seal engraving. Photocopies of more than 400 ancient seal engraving are included in the book, together with photocopies of Han's private collection of seals and his own works of seals. In addition, the book selects more than 600 pictures of extracts from various books of ancient seal impressions and seal materials to provide the readers with a comprehensive introduction to the art of Chinese seals.
