The Spanish Habsburgs had a famous family motto: Plus Ultra, or "Further Beyond."
According to ancient myth, during the trials of Hercules, he traveled as far as the Straits of Gibraltar (known in Antiquity as the Pillars of Hercules), which were inscribed with the motto Nec Plus Ultra, or Nothing Further Beyond. The implication was that there was nothing of interest in the open ocean and that venturing out further was death.
Emperor Charles V, in his role as King Charles (Carlos) I of Spain, made Plus Ultra his motto, reflecting Spain's ambitions over the New World.
To this day, the phrase Plus Ultra is on the flag of Spain.
