The writing prompts invite postcrossers to write about a different topic on their postcards’ messages every month. These are just suggestions though — if you already know what you want to write about, or the recipient gives you some pointers, that’s great too!
Every country has inventors, talented people who brought something new to the world. Maybe it’s a novel product or an ingenious process, a breakthrough in some field of science… or maybe a cultural invention, like a new musical instrument or a different way to look at things! This month, we’re exploring these inventions and sharing some of our country’s creative heritage with the world.
So, I’ll go first. It’s a hard job to pick one of the Portuguese inventions… but I think one of the earliest ones we’re taught in school is the sea astrolabe.
This is an instrument that was used by sailors to determine their location at sea, based on the altitude of the sun at noon or of a known star at its peak, during the night. By measuring the angle of the star with the horizon, they could calculate the latitude of their ship in the globe, thus getting the information they needed to guide the ships to the right destinations. The oldest Portuguese astrolabe was discovered a few years ago in the wreck site of the ship Esmeralda, which sank in 1503 off the coast of Oman.
What about your country? Which inventions did your fellow citizens bring to the world, and which are you most proud of? Do share these in the postcards you write this month… and also in the comments below, if you can — we’re always curious to learn new things! 😊
