Here's a breakdown of the metaphor:
* The sun never sets: This implies a constant presence, something that never fades away. It's often used to describe vast empires that stretched across many time zones, meaning the sun was always shining on some part of their territory.
* Glorious human achievement: This refers to a significant accomplishment that inspires awe and admiration. It could be a scientific discovery, a work of art, a social movement, or anything that has positively changed the course of history.
Therefore, the phrase conveys that the achievement is so impactful and important that its influence will continue to be felt for generations to come, even after the people who created it have passed away.
Examples of how this phrase could be used:
* "The moon landing was a glorious human achievement, and the sun shall never set on its impact on our understanding of space."
* "The signing of the Declaration of Independence was a moment that changed the world, and the sun shall never set on the legacy of freedom it represents."
* "The development of the internet is a glorious human achievement, and the sun shall never set on its power to connect people and spread knowledge."
