The story behind it
Word for word the phrase says “to light”, which in natural English becomes “toward the light”. It is a short, direct statement of direction, with no verb needed.
It is not a quotation from a particular ancient author. It is a motto in the Latin tradition, adopted by many schools and universities to sum up the purpose of education, which is to move from not knowing to knowing.
The image of light standing for knowledge and truth is very old in European writing, and it is why the phrase suits classrooms, libraries and graduation gifts. The exact wording and the schools that use it vary, so check the source of any specific inscription.
How to use “Ad lucem”
A fitting inscription for a school, a library or a graduation gift, or a personal motto for someone who values learning and growth. It also works as a short tattoo or a caption for a photo of a sunrise or an open window.

Common mistakes
- The accusative lucem is required after ad. Writing “ad lux” is wrong, because lux is the nominative form.
- It is not a line from a famous Roman author. Treat it as a modern motto, not an ancient quotation.
- Do not confuse it with “Lux in tenebris” (“light in the darkness”) or “Lux et veritas” (“light and truth”), which are different phrases with different meanings.
- The word ad shows direction toward the light, so “from the light” would be a different phrase altogether (ex luce).
