 In artem analyticem isagoge by François Viète

Tours original edition. The BnF catalogue establishes the title and date. Facsimile: gallica.bnf.fr/ark:/12148/bpt6k108865t . Folio 5r contrasts logistica numerosa and logistica speciosa; a scholarly reproduction and translation appears at www.uv.es/puigl/historias67.pdf . The latter is used for the specific terminology; the modern biographical discussion supplies the notation and homogeneity context.
