He was fascinated with astrolabes and was interested in sailing.

An astrolabe is an instrument that was used for centuries to mark the positions of the sun and stars.

星盘是数百年来用来标记太阳和恒星位置的仪器。

The astrolabe sometimes seems to have more personality than the monk, probably because of the paucity of biographical information available.

星盘有乎比这个修士更有个性，但也可能是因为关于修士的传记资匮乏。

The astrolabe had to be kept in a freshwater bath for two years to get all the salt off it.

Today just over 100 mariners astrolabes are known to exist in the world but add this one to the tally.

今天，世界已知的水手星盘只有100多个，但这个数字还要加一个。

The place is stored with great variety of sextants, quadrants, telescopes, astrolabes, and other astronomical instruments.

As Ferdinand Magellan, the first known circumnavigator, started out in 1519, he had at least an astrolabe and compass.

Instruments called an astrolabe and a cross-staff could measure latitude—how far north or south from the equator the ship was.

称为星盘和十字杆的仪器可以测量纬度——这艘船离赤道有多远。

They were first used by astronomers hundreds of years B.C. and sailors used them in the Middle Ages until astrolabes were replaced by sextants.

公元前数百年，天文学家首次使用它们，水手们在中世纪使用它们，直到六分仪取代了星盘。

Over the next 4000 years, humans developed all sorts of clever computing devices, like the astrolabe, which enabled ships to calculate their latitude at sea.

在接下来的4000年种，人类开发了各种聪明的计算设备例如星盘，可以使船只在海计算其纬度。
