Future generations of people, especially those who will live after us.
The artist hoped that his work would be appreciated by posterity.
Posterity → It is formed from "post-" (meaning after) and "-erity" (derived from the Latin "serere", meaning to sow or to plant). The word refers to those who are born after us, or the descendants that come after us, as if they are the seeds sown for the future.
Think of 'after' ('post-') and 'sowing' ('serere') to remember that 'posterity' means the descendants who come after us.
