Tycho Brahe (1546 - 1601)

Simplicibus itaque verbis gaudet Mathematica Veritas, cum etiam per se simplex sit Veritatis oratio.
So Mathematical Truth prefers simple words since the language of Truth is itself simple.
Epistolarum astronomicarum liber primus (1596), General Preface: In J L E Dreyer (ed), Tychonis Brahae Astronomi Dani Opera Omnia 6, 23.
Note that Veritatis simplex oratio est is a quotation from Seneca (which Tycho's original readers probably recognized).
