How did Giambattista Vico revise Scienza nuova after its first publication?

After the initial 1725 publication of Scienza nuova met with indifference, Giambattista Vico began a total revision and restructuring of his masterpiece. Because he had originally been forced to reduce the text by two-thirds due to financial constraints, he sought to organize and systematize his ideas more effectively.1

This process involved several stages of development, including the creation of various "fragments" between 1729 and 1732. His efforts culminated in a second edition, which was significantly restructured compared to the first. Ultimately, Vico produced a definitive version, published posthumously in 1744 and labeled the terza impressione (third edition), which followed a greatly revised and distinct plan. Throughout these revisions, Vico transitioned from his initial, more poetic mode of thought toward a more systematic presentation of his philosophy of history.1
