Seeking a Language in Mathematics 1523-1571

Why no mention of Thomas Harriot's _Artis Analyticae Praxis_?

(ob. discl., I did the typesetting for Springer's translation by Muriel Seltman and Robert Goulding: https://www.goodreads.com/book/show/1098132.Thomas_Harriot_s... )

Not just the math, but the English, too, is quite interesting.
