A 1684 London astrology treatise by John Kendal, printed by J. Playford for C. Hussey, offering tables of the equation of arch of direction for casting nativities. The pictures are plain typeset tables: a Museum Britannicum library stamp and a page of numeric columns under the heading Tabula Æquationum, with ruled borders and small printed figures. A designer might borrow the dense tabular grid, bold old-style capitals and ruled frames as a structure for data-driven layouts.
