The Male Name "Mantas"

[FancyMancy]

I have heard of the Male name "Mantas". It is European. One website says it means intelligent, where another says it is to do with wealth. I realised that Mantas backwards is Satnam. Is the name jewish in origin? I realise that a lot of countries have been christianised, so they would have christian names, and I suppose it is a christian name in European countries.
