Beatrice comes from Latin and is traditionally translated as "she who brings happiness" or "blessed one," a meaning that gained lasting resonance through its association with a guiding figure in classic literature. The name is often read as carrying a sense of joy that uplifts others, not just the person who bears it.
To unfasten the tongues Mercury must be in its house and it is efficient with those who Mercury rules. - Picatrix (Andalusia, ~1000.AD)
