Motto of Shepherd College, Shepherdstown, West Virginia, USA.

Motto of German Emperor Charles V (1519-1556). It is also written as, Plus ultra and it is translated as, "Thus far and further".

The limit, perfection, highest point, or peak of achievement or excellence; the pinnacle, the ultimate. The most profound degree of a quality or condition.

Although the literal sense of the phrase makes it possible to be used as a term expressing prohibition, in the sense of "no further may you go", its primary use indicates the supremacy of a product, a literary work, a system, etc.

Based on a German source, Hercules is said to have settled in Cadiz, Spain, where he erected columns as a monument with the inscription: "These are the limit stones of Hercules" with the idea that this was the edge of the world.

Many Germans believe the phrase refers to something that is "the best", "the utmost", or "nothing better".
