In the Bible there didn't exist rainbows until after the flood. God put the rainbow in the sky as a proof that he would never flood the Earth again. Rain
oooor... in Norse mythology the rainbow was supposed to be the bridge that connected the gods to earth, like a bridge that gods use to travell down to earth or something like that ╮( ̄▽ ̄)╭
OMFG WHAT A USELESS GOD(/TДT)/
i feel so sorry for him ಥ﹏ಥ
