Recently Catherine Jami and I have found the manuscript of the Lifa wenda Dialogue on Astronomy) by Jean-Francois Foucquet (Fu Shengze , 1665-1741) at British Library. Together with the other, partial, but, otherwise identical, version, which she had located at the Vatican Apostolic Library, the manuscript, especially Book V, Part 1, from the British Library, gives us the detail of how Kepler’s forst and second Laws was introduced into China as early as in the 1710’s. This means that we can go back in the history of the introduction more than two decades earlier than the so far believed date.
