弯刀

As they approached the piazza del popolo , the crowd became more dense , and above the heads of the multitude two objects were visible : the obelisk , surmounted by a cross , which marks the centre of the square , and in front of the obelisk , at the point where the three streets , del babuino , del corso , and di ripetta , meet , the two uprights of the scaffold , between which glittered the curved knife of the mandaia
当他们接近波波罗广场的时候，人群愈来愈密了，在万头攒动的上空，可以看到两样东西，即方身尖顶的石塔，塔顶上有一个十字架，标明这是广场的中心和耸立在石塔前面，耸立在巴布诺街，高索街，立庇得街三条路的交叉口上的断头台的那两根直柱，在这两根直柱之间，悬挂着一把闪闪发光的弯刀。
