Barnaby comes from the Aramaic Barnabas, translated as "son of encouragement," a name carried by a companion known in scripture for consistently backing others rather than seeking attention himself. It suggests support offered steadily, the kind that shows up in someone's corner rather than the spotlight.
If you ignore something use Mercury because in relation with this it means renovation and growth, resolute influx and quick response. - Picatrix (Andalusia, ~1000.AD)
