First mentioned as Santa Claus driving the name of the eight elk is the "Christmas Eve" of the poem,

These eight elk are called: Dasher, Dancer, and Vixen Prancer; Come, Cupid, and Blitzen Donder (and Blixem Dunder, and Blixen Donner).

Later in the "Red Nose Reindeer Rudolf," the famous Christmas Song appeared in the name of the ninth elk.

Yes, Rudolph is the legend in charge of guiding the sled, but also the most favorite of Santa claus.

最初提到为圣诞老人驾车的八只麋鹿的名字的是在《圣诞前夕》这首诗中，

这八只麋鹿分别叫做：Dasher，Dancer，Prancer and Vixen；Come，Cupid，Donder and Blitzen（Dunder and Blixem ,Donner and Blixen）。

后来又在《红鼻子驯鹿鲁道夫》这首著名的圣诞歌曲中出现了第九只麋鹿的名字，它叫Rudolph，也就是传说中负责引导雪橇的那只麋鹿，也是圣诞老人最喜欢的那只麋鹿。
