The cross staff was important in navigation during the late Middle Ages and the Renaissance because it allowed sailors to measure the angle of celestial bodies above the horizon. This tool enabled navigators to determine their latitude with greater accuracy while at sea. By aligning the cross staff with the celestial object and the horizon, sailors could take reliable readings, which significantly improved maritime navigation and exploration. Its use laid the groundwork for more advanced navigational instruments that followed.
A Cross Staff and a Quadrant are Instruments that measure Latitude.

Staff personal hygiene is incredibly important in maintaining a safe and clean environment, especially in food service and healthcare settings where cross-contamination can occur. Proper personal hygiene practices help prevent the spread of bacteria and viruses, reducing the risk of foodborne illnesses and infections among staff and customers/patients. It also promotes a positive image of professionalism and cleanliness in the workplace.
