An astrolabe is a primitive angle-measuring tool. It can be used to - very in-exactly! - measure the altitude above the horizon of a celestial body like the Sun, Moon or Polaris in order to calculate your position.

Answer:Slave life varied greatly depending on many factors.
Life on the fields meant working sunup to sundown six days a week and having food sometimes not suitable for an animal to eat. Plantation slaves lived in small shacks with a dirt floor and little or no furniture. Life on large plantations with a cruel overseer was oftentimes the worst. However, work for a small farm owner who was not doing well could mean not being fed.
The stories about cruel overseers were certainly true in some cases. The OVERSEER was paid to get the most work out of the slaves; therefore, overseers often resorted to whatever means was necessary. Sometimes the slaves would drive the overseer off the plantation in desperation. When slaves complained that they were being unfairly treated, slaveholders would most often be very protective of their "property" and would release the overseer.
n some cases, a driver was used rather than an overseer. The difference between the overseer and the DRIVER was simple: drivers were slaves themselves. A driver might be convinced by a master to manage the slaves for better privileges. Drivers were usually hated by the rest of the slaves. These feelings often led to violence.
Large plantations often required some slaves to work in the plantation home. These slaves enjoyed far better circumstances. DOMESTIC SLAVES lived in better quarters and received better food.

Domestic slaves did not often associate themselves with plantation slaves. They often aspired to arrange courtships for their children with other domestic slavesExplanation:
