For the last day of , take a closer look inside Opera Mathematica by Samuel Marolois, a fascinating 17th-century work exploring the connections between mathematics, art, architecture, and perspective.

Filled with beautifully detailed engravings, the book demonstrates how mathematical principles could be used to understand and represent the world around us.

In these pages, you can discover everything from geometric shapes and conic sections to fascinating studies of perspective, light, and distance. Notice how carefully drawn lines illustrate the way we see objects in three dimensions, while intricate diagrams explore the construction and measurement of different shapes.

More than just a collection of mathematical calculations, Opera Mathematica shows how science and creativity have gone hand in hand for centuries.

Which of these remarkable illustrations catches your eye the most?

Another one for !

In this chapter of Mathematicall magick (1648), John Wilkins shows how it is 'possible to contrive such an artificiall motion, as may be equally swift with the supposed motion of the heavens'.

If the gear in this illustration is turned one thousand times an hour, the sail at the top will be turned 1000000000000 times, and move faster than a star. Impressive!

In 1671, Friedrich Martens travelled to Svalbard and around Greenland as ship's surgeon on the 'Jonas im Walfisch' or 'Jonah in the Whale'. These engravings of a whale & fin whale are from the diary he kept, first published in 1675, where he recorded the area's flora, fauna and whaling industry.
