Noun:
a silver-white metallic element of the platinum group that resembles platinum; occurs in some copper and nickel ores; does not tarnish at ordinary temperatures and is used alloyed with gold in jewelry希腊神话中，战争女神雅典娜Athena出生时就全副武装，所以她小时候喜欢的 并不是一般女孩子喜欢的文静游戏，而是真刀真枪的格斗。有一次她与自己的好朋友、河神法厄同的女儿帕拉斯Pallace用长矛练习格斗。两个女孩打得 正酣时，宙斯看到了这一切，担心自己的女儿受伤，于是就在两人之间降下了一面羊皮盾牌，护住了雅典娜。结果帕拉斯的长矛被盾牌挡住，而正当她为这突然出现 的盾牌纳闷时，雅典娜的长矛已经刺穿了她的身体，雅典娜因为误杀了自己的朋友而伤心不已。为了纪念她，雅典娜把自己的名字改成了帕拉斯·雅典娜 Pallace Athena，并为帕拉斯制作了一尊雕像并放在宙斯的神像前。
特洛伊国王伊罗斯在修建特洛伊城时，祈求先祖宙斯的兆示，看神灵是否同意他的建城计 划。第二天，伊罗斯在自己的帐篷前捡到从天上落下的帕拉斯神像。这意味着宙斯同意将该城置于他及其女儿雅典娜的庇护之下。从此以后，这尊帕拉斯神像就成了 特洛伊的守护神。英语单词palladium就来自帕拉斯的名字，表示“守护神”。著名化学家Wollaston用它来命名他新发明的金属元素钯。
