In this case presumably the main difference is not PowerShell vs. bash but iwr vs. wget? Because I think this is roughly equally bad (untested):

    for page in {1..1119}; do
        iwr "https://codex-atlanticus.ambrosiana.it/assets/2000/000R-$page.jpg" -OutFile "000R-$page.jpg"
        iwr "https://codex-atlanticus.ambrosiana.it/assets/2000/000V-$page.jpg" -OutFile "000V-$page.jpg"
    done

wouldnt this mess up the order? I think you are supposed to view it like R1, V2, R2, V2, etc

Maybe what rarely works well for NoMoreNicksLeft is having a gigabyte of JPEGs in a single HTML chapter inside the epub? In that case you could do something like divide the files into 373 "chapters" of 6 pages each?

One of the fragmentary editions I linked on the Archive uses the .cbr Comic Book Reader format; perhaps that is a better format than .epub for high-resolution scans of every page?

Oooh... I have even less luck with epub, when the pages are an image-per-page.

Oh, is .cbz that simple? Does it use the file order of the zipfile members or some other order? (https://acbf.fandom.com/wiki/ACBF_Editor_-_Creating_Metadata says it uses alphabetical order, which is the wrong order in this case.)

It may be useful to use zip -Z store. JPEG data isn't going to get much benefit from another layer of LZ77.

Nitpick: "da Vinci" wasn't our homeboy's name. That just means "from Vinci". He was "Leonardo", like many other people, so we added "da Vinci" to clarify which Leonardo we meant, just like you might say, "Jessica from church came by," to clarify that you didn't mean Jessica the ex-girlfriend. Surnames weren't very widely used in Italy then.

It's like "Jesus of Nazareth"; you wouldn't talk about "other OfNazareth's biographies". Ain't grammatical.
