Philosophical transactions of the Royal Society of London
The Philosophical Transactions of the Royal Society of London, published in London in 1666, was a scientific journal issued by the Royal Society for its fellows and natural philosophers. The first plate charts observations of Jupiter's moons and Saturn's rings in ruled tables with small circles and dots, while the second shows faint geometric constructions of circles, lines and angles drawn in pencil. A designer might draw on the diagram grids, orbit rings and precise line work for technical or scientific graphics.
