地圖綜要 : 三卷（安南圖）

地圖綜要 南明弘光元年（1645），吴学俨等编纂，李釜源鉴定，朗润堂藏板。 该书为明末军事防务地图集，涉及诸多江防、海防、边防等相关地图和解说，军事意味明显，这与成书背景有密切关系。该书在江南刊刻成书之际，清军已大举入关，大明王朝覆灭，仅剩南明小王朝残喘于南方，军事防务至关重要。也因其明显的南明立场，该书被列为四库禁毁书。全书分总卷、内卷和外卷三部分。燕京藏本共八册，书前序言、凡例和目录的总卷部分缺失。 总卷论及大明疆域沿革、军事防守要害、各省道里等内容，地图有《華夷古今形勝圖》，未画方，标绘各府所在，在空白处标注史地简介；《天下各鎮各邊要圖》，未画方，标注北方边防各山口关隘、东南海防、西南边防等；《京省合宿分界圖》，未画方，图上方标注各星宿，对应大明各府州；《天下輿地分里總圖》，计里画方，每方五百里，绘制两京十三省各府所在地。 内卷为两京十三省的建置总数、分里图、分界图、各府州县志、总论及事宜，其中，建制总数包括府州县卫所及各类机构数量、户数、口数、税、钞、丝、绢、盐、马草等数量；分里图采用计里画方，分别绘制两京十三省各府、州、县、卫所及山川河流名；分界图则以突出府界和州县的相对位置，并不追求里程的准确性，因此，与分里图相比，不仅删去了山川地名和解说，而且地图变形较大，以便于较为疏朗地标注各府州县地名；各府州县志则包括省内各府的山川河流、土产古迹、名宦人物等通常为方志所记载的内容；总论高度概括各地历史和地理形势；事宜则多论及该地的军事守备要领。每省分里图和分界图各一幅。外卷主要为江防、海防、边防相关地图和图说。包括《長江會源分里全圖》《江防全圖》《漕河分里圖》《黃河分里圖》《海防全圖》《日本島夷入寇要害圖》《海運分里圖》《九邊總圖》及九边分图《遼東沿邊圖》《薊鎮沿邊圖》《宣府沿邊圖》《大同沿邊圖》《山西沿邊圖》《大同山西二邊分里合圖》《延綏沿邊圖》《寧夏沿邊圖》《固原沿邊圖》《甘肅沿邊圖》《四夷總圖》及四夷分图《東北諸夷圖》《朝鮮圖》《日本圖》《琉球圖》《東南海夷圖》《東南濱海諸夷圖》《西南海夷圖》《安南圖》《迤北西番諸夷圖》《西域圖》《朔漠圖》等。在外卷诸图中，以《江防全圖》规模最大、绘制最为详细，并附有详细的解说，显然，这与当时南明小王朝偏居南方的局势密切相关，天堑长江实际上已经成为南明小王朝最后的屏障。 在图例上，府用正方形，州用菱形（包括土州），县用椭圆，卫所用椭圆外加四方短线，但图上大多数卫所并没有标志。 李釜源名茹春，崇祯十年（1637 年）进士，知华亭县。 《中國古籍善本書目》著录。 8册64图，墨刻本，中文，尺寸24.7 x 16.3 cm，计里画方。Harvard-Yenching | Rare Book | T 3080.7 2925，Harvard-Yenching | Microfilm | FC9113， Master Microforms | Offsite Storage | Film Mas 34483；Hollis Number：008094513 吴学俨等 朗润堂
