KEMPTHORNE, Captain John (1651-1692), attributed to. Fine Manuscript Coastal Chart: "A Draft of the Ladroon Islands on the Coast of China near the Mouth of the River Canton". [Southeast China]: 1687.

Single sheet, float-mounted and framed (25 4/8 x 38 inches to the neat line). Fine original pen and ink and watercolour drawing of coastal region of China near the mouth of the 'Canton' (Pearl/Hsi Chiang River), with two coastal profile drawings and 32 rhumb lines radiating from a fine, large multi-colored compass rose, and a scale of leagues, decorated with mountains on the islands, and 'Paddy Grounds' indicated along the river.

An original 17th century English Thames School manuscript sea chart, bearing close resemblance to extant charts drawn by Captain John Kempthorne who sailed in Chinese waters in the service of the East India Company in 1686-88. R.A. Skelton in Explorers Maps, fig. 115 illustrates Kempthorne's 1687 chart in the British Library of Amoy, also in southeastern China, which is very similar stylistically and in lettering to this chart. Macao is named and shown by a walled town symbol. In the Hong Kong area, all of Lantau Island is delineated, with numerous islands nearby, one of which is doubtlessly Hong Kong. Kempthorne's sketches of his Asian travels from ca. 1688-90 are in the Papers of Sir Hans Sloane at the British Library. Kempthorne was the eldest son of Sir John Kempthorne (circa 1620-1679), an officer in the English Royal Navy during the Second and Third Anglo-Dutch Wars. He joined the East India Company in 1682 and was in its service until 1688. During this time he is known to have sailed in Chinese waters as master of the Indiaman the Kempthorne.

约翰·肯普索恩 (1651-1692)，被认为是“中国沿海珠江口附近Ladroon岛草图”作者。【中国东南部】：1687年。

单页纸质，立体裱褙及装框 (距离内图廓线64.77 x 96.52厘米，或25.5 x 38 英寸)。精美原装墨色和水彩画，绘有中国珠江口附近的沿海区。图上有两个沿海分布图，32条由一个多色大罗经盘放射开来的恒向线和一个联盟缩尺图，并饰有岛上的山脉及沿江的稻田。

这是一张原装17世纪英国泰晤士学院的手稿海图，与现存的由约翰·肯普索恩上校绘制的地图极为相似。后者曾在1686年至1688年期间因受雇于东印度公司而航行于中国海域。

R.A. 斯凯尔顿在《探险家地图》（Explorer Maps）的115号插图中描述了一张肯普索恩于1687年绘制的地图，其在文体和形式上都与这张地图非常相似。前者在当时存于中国东南部的厦门大英图书馆。

澳门由一个古城墙符号命名并指示。在香港地区，大屿山所有部分都被勾勒了出来，无数岛屿环绕其周围，而香港则毫无疑问是其中之一。

肯普索恩在大约1688年到1690年间行至亚洲的记录被载于Papers of Sir Hans Sloane，并存放于大英图书馆。肯普索恩是约翰·肯普索恩爵士的长子 (约1620-1679)，约翰•肯普索恩爵士曾是第二和第三次英荷战争期间的英国皇家海军军官。肯普索恩于1682年至1688年期间受雇于东印度公司。在此期间，他成为知名的航行于中国海域的印度商船船长。
