Description: Song Dynasty Rivership with Xuanfeng Traction Catapult from the Wujing Zongyao, the 1510 edition of the Ming Dynasty. The photographs are part of my book. You're welcome to use them on Wikipedia so long as you list my book "Chinese Siege Warfare: Mechanical Artillery & Siege Weapons of Antiquity" by Liang Jieming (ISBN 981-05-5380-3) as the source. I hope that helps. Cheers, Leong Kit Meng (Liang Jieming) <liang_jieming@history-forum.com>
