This is a new methodology for unlocking hard “sciences” beyond western epistemic approaches. The paper illustrates reading and use of Mathematics from non-written linguistic texts archived by precolonial Shona people of Southern Africa, theorizing that precolonial Mutapa Empire of Zimbabwe, globally excelled in both spiritual and material culture. It unveils generation, processing archiving and retrieval of ‘hard science’ knowledge through linguistic styles demystifying the belief that sophisticated knowledge of hard sciences like Mathematics, Physics, Engineering etc depends on writing. It illustrates that fields of advanced Mathematics like Algebra, Trigonometry, Geometry and even Calculus, were developed and applied in engineering, architecture, metallurgy, mining etc of the Mutapa era. The paper explores the Mathematics by unpacking Mathematical archives of proverbs, conundrums and idioms to give a glimpse of a whole new world of Epistemology unlocking ‘mysteries’ of the Southern Africa’s past. It opens a new chapter in Anthropology.
