Merles, Balthazard-François de, author · 1675 · [4th quarter of 17th century] · 4 pictures

A manuscript of handwritten astronomical notes and diagrams by Balthazard-François de Merles, probably made in France in the late seventeenth century, apparently for personal study of eclipses and planetary motion. The pages show ruled horoscope-style charts with planetary symbols and numerals, ink calculations in columns, and a written page beside diagrams of concentric orbital circles.
