                                                                                                                               苏州园林的花窗
        ①游览苏州园林,走在蜿蜒迂曲的回廊上,或歇息在厅阁亭榭内,没有人不被那些设计精美、做工考究、形态各异的花窗吸引。透过这些花窗,墙外的景致若隐若现,亦真亦幻,别有意趣。
        ②苏州园林的花窗式样之多,号称世界之最。光窗框就有多边形、圆形、月芽形、宝瓶形、如意形等多种形状;窗芯更是样式无穷,变化多端,常见的有菱花、书条、套方、鱼鳞、钱纹等等,各种图纹层层相套、交错穿插,衍生出无尽的缤纷意态。花窗犹如墙之眉眼,以其多变的造型、精美的纹饰使之顾盼有姿。它既可使平直的墙面一扫沉闷、单调之感,又可因不同的光影搭配,而在白粉墙上“绘就”一幅幅水墨画,美不胜收。
        ③苏州园林的花窗不仅是一种装饰,也是文人园林文化的反映。图案中有许多象征文人风雅的符号,如植物中的松、柏、竹、兰花、菊花、荷花、梅花,还有表示高洁的冰纹等。特别值得一提的是,得中国“书画同源”之助,苏州窗饰图案中还有用文字塑成、连缀成诗句的“诗窗”,在世界上绝无仅有。如退思园“九曲回廊”,廊壁上开辟了九孔图案雅致的花窗,分别砌上李白《襄阳歌》中的名句“清风明月不须一钱买”九字,诗被物化了,景被诗化了,诗境、园景融成一体。
        ④苏州园林的花窗还是裁剪风景的取景框,它丰富着景致的层次和色调,使人置身于咫尺之地,而能获得意想不到的观赏效果。透过一个又一个花窗,看园中竹树摇曳,楼阁隐现,顿觉片山有致,寸石生情;更有旭日夕晖、春华秋实,替换着窗中的色彩和形态,使整个园林充满诗情画意。
        ⑤历代造园家匠心独运,把苏州园林中的每一个景点都建造得非常精细,即使是那些花窗,也都是一件件艺术品,经得起把玩,耐得住寻味。(选自《瞭望新闻周刊》,有改动)
