Summary
[edit]DescriptionMao Kun Map - stellar diagram 3 - P1100092.JPG |
This navigational chart is one of the stellar diagrams included in the Wubei Zhi (chapter 240, folio 23 v.). The chart specifies the guiding stars enroute from Poulo Rondo to Ceylon. It appears as stellar diagram III in "Appendix 6: Four stellar diagrams" of Mills's Ying-yai Sheng-lan: 'The Overall Survey of the Ocean's Shores' [1433] (1970). Note: The Mao Kun map itself comprises 40 pages in chapter 240 of the Wubei Zhi from folio 2 v. to 22 r. (Mills 1970, 238), while these four stellar diagrams come after the map. |
