Objectum oculi : publicae disputationi propositum in alma, & electorali universitate Ingolstadiana
Objectum oculi is a 1714 Latin academic disputation printed at Ingolstadt by Thomas Grass, presented by the students Leonardo Hausman and Herculanus Karg at the university there, and concerned with vision and optics. Its pictures are small printer's ornaments: a repeating border of stylised floral and figural motifs above a large decorated initial Q framed by scrolling acanthus leaves, a pattern a designer could adapt for borders, drop caps, or framing devices.
