What is the origin of the phrase tread lightly?

The origin of the phrase tread lightly is unknown, but the most famous example dates back to the poem “Aedh Wishes for the Cloths of Heaven” by W. B. Yeats on Yeats writes, as one of the most famous examples of all time:

I have spread my dreams under your feet;

Tread softly because you tread on my dreams.

Here, Yeats uses the phrase metaphorically, begging the recipient not to tread on – and crush – his dreams. 

According to Etymonline, the word tread comes from the Old English tredan, meaning “to step on, traverse, or trample.” This comes from the Proto-Germanic tred, which has roots meaning run, step, or walk.
