Finely executed Jesuit missionary map of the modern Chongming Island, at the mouth of the Yangtze River.
The island has been divided into 3 districts (north, central and south). The map provides a remarkable amount of detail about the island, including its then population of 1.2 Million inhabitants. The majority of the tables give the numbers of Christians in various parts of the island. There is also a significant discussion about the activities of the Orphanage run by the missionaries.
The map was produced under the direction of the Roman Catholic Apostolic Vicariate of Kiang-nan, a missionary jurisdiction in mainland China, comprising the two imperial provinces of Jiangsu and Anhui, often referred to as Jiangnan or Kiang-nan.The map was produced at Zi-ka-wei, where the the Jesuit Fathers established themselves in 1847, near the tomb of Paul Xu, at which period of the orphanages of the mission were commenced.
