The name Leo: origin and meaning
Leo is a name of Latin origin, meaning "Lion". It has travelled across Europe for centuries — its earliest bearer in the Christian tradition is Pope Leo the Great (5th century) and 12 other Pope Leos, and in modern times it has become widely recognised through cultural figures such as Leo Tolstoy, Leo Messi (Argentinian footballer).
In Spain, the name connects to Pope Leo the Great (5th century) and 12 other Pope Leos, which keeps it firmly embedded in the Catholic naming tradition and the local saints' calendar.
