Wall Street Bull
The Wall Street Bull, which is also referred to as Charging Bull or the Bowling Green Bull, is a 3200-kilogram bronze sculpture by Arturo Di Modica that stands in Bowling Green Park near Wall Street in Manhattan, New York City. Standing 11 feet(3.4m)tall and measuring 16 feet(4.9m)long, the oversize sculpture depicts a bull, the symbol of aggressive financial optimism and prosperity, leaning back on its haunches and with its head lowered as if ready to charge.
The sculpture is both a popular tourist destination which draws thousands of people a day, as well as “one of the most iconic images of New York” and a “Wall Street icon” symbolizing “Wall Street” and the Financial District.
华尔街铜牛
华尔街铜牛也被称为金融牛或者博林格林牛，这是一座重达3200公斤的铜塑雕像，设计者是阿图罗 迪 莫迪卡。这头牛坐落于纽约市曼哈顿华尔街附近的博林格林公园，11英尺(3.4米)高，16英尺(4.9米)长。这大型雕像的造型为一头牛，腰部后倾，脑袋低垂，似乎准备发起进攻，而这象征着财政繁荣，股市大涨。
现在，这座雕像是著名的旅游目的地，每天吸引着成千上万的游客，同时也是纽约的代表和华尔街的标志形象，象征着整个华尔街和金融区。

铜牛诞生背景
1989年10月13日星期五下午收市前一个小时，道 琼斯工业股票平均价格突然开始迅速下跌，抛售的指令蜂拥而至，以致不能按时收市。收市时，华尔街股票总市值在半小时内跌掉了约2500亿美元，被世人称为“黑色星期五”。由于这种跌势类似两年前的“黑色星期一”，因而世界各地的股票市场顿时陷入惶惶不安之中，唯恐“黑色星期一”再次降临。
在1987年纽约股市崩盘之后，阿图罗 迪 莫迪卡有了创作的灵感。他说：“当我看到有人失去了一切，我感到非常难过，于是我开始为年轻的美国人创作一件美丽的艺术品。”为了筹资，他卖掉了家乡西西里祖传农场的一部分，总共筹得资金36万美元，最终完成了雕塑。
