A compass offers the most significant message to the recipient in the smallest, most interesting package possible. It’s a symbol for direction, staying the course, for adventure, discovery, science and human inventiveness.
This compass is a replica of an original 18th century sundial compass at the National Maritime Museum. The museum has a stunning collection of navigational instruments, including depth gauges, speed indicators and of course compasses. They are objects of beauty that fire the imagination.
Finding your way is easy these days, thanks to satellite navigation. In the old days, navigation was much more difficult – especially at sea. Old navigational instruments, such as this bronze pocket compass, will give you an idea of how inventive the sailors of the past were.
Right up until the 20th century, ships still depended on the sun, moon and stars to navigate the seas. Sailors used the earliest navigational instruments – the astrolabe, the cross-staff and the back-staff – to determine how far north or south they were from their point of departure. All instruments worked with the same principle: they measured the angle of the sun (or star) against the horizon.
As seafaring became increasingly important, sailors needed more precise methods to determine their position. They developed new instruments, such as the octant and sextant. These new instruments worked according to the same principle, but gave much more precise readings than their predecessors.
