as long as i have researched i have found here in this presumed book from Peano
https://archive.org/details/arithmeticespri00peangoog/page/n6/mode/2up
that actually peano has defined the 1 as the first natural(page 1) since(acording to the book) 1 is not the successor of another natural number; but in another places like wiki and wolfram
https://mathworld.wolfram.com/PeanosAxioms.html https://en.wikipedia.org/wiki/Natural_number
i have found the discrepancy that they define 0 as the first natural
my question here is not about the ground truth of the sentences "0 is element of Naturals" but rather i would like to ask what was the true first axiom of peano?, the book up there is the right one to search? and if peano really wrote "1 is element of Naturals" instead the "0" version, who corrected him? or who was the person that historically is considered to put the 0 in the Naturals?
