In 1570, the invention of the log-line and chip log revolutionized maritime navigation by providing a simple yet effective method for measuring a ship's speed through water. The log-line consisted of a knotted rope thrown overboard, while the chip log was a floating piece of wood that helped sailors calculate speed based on the time it took for the knots to pass through their hands. This advancement greatly improved navigational accuracy and efficiency, aiding in the age of exploration.

The invention of the log-line and chip log for speed measurement in 1570 improved navigational accuracy, influencing exploratory literature and poetry. Poets like John Milton celebrated the age of discovery, using their works to evoke the excitement and peril of maritime adventures.
