horizon

The Sailor's Word-Book

The apparent or visible circle which bounds our vision at sea; it is that line which is described by the sky and water appearing to meet. This is designated as the sensible horizon; the rational, or true one, being a great circle of the heavens, parallel to the sensible horizon, but passing through the centre of the earth.
