Are the commas correct in this stanza?

Question

Each artifact,

One by one, he finds

He puts under

The scope and then knows

Why.

Answer 1

Each artifact, One by one, he finds He puts under The scope and then knows Why.

If you format the poem as a sentence you can see more clearly that your commas are working perfectly. :)

The line "One by one, he finds" looks and sounds the oddest but it is properly punctuated based on the understanding we discussed in the previous question.

Answer 2

I find the placement of "he finds" to be confusing, so it makes it hard to decide if the commas are really correct. Would you consider:

Each artifact he finds,

One by one,

He puts under the scope

And then knows

Why.
