补充资料：吴宽(1435～1504)
明代诗人、散文家。字原博，号匏庵。长洲（今江苏苏州）人。明宪宗成化八年(1472)，会试、廷试获第一，入翰林，授修撰。曾侍孝宗东宫，孝宗即位，迁左庶子，预修《宪宗实录》，进少詹事兼侍读学士，后又升任吏部右侍郎、礼部尚书等。吴宽作风高洁，不受时尚左右，而以清正自守。死后谥文定。少壮好学，于书无所不读,尤喜《左传》、《汉书》、唐宋大家散文,最喜苏轼文章。他学有根底,诗文和平恬雅,有典则。《明诗评》说："文定力扫浮靡，一归雅淡，诗如杨柳受风，煦然不冽；又如学究论天下事,亹亹竟日,本色自露。"代表作有七律《悼沈癯樵画史》、《题杨铁崖墓铭后》、《送张兼素出知施宗州》、《谢顾良弼李世贤携酒过访》等，七古有《赋黄楼送李贞伯》等。吴宽兼工书法，字亦学苏东坡。诗文集有《家藏集》77卷,其中诗30卷,文40卷，为吴宽自订。后7卷疑为其子吴奭所增益。
