The Parable of the Sower

[zarajara]

Gentlemen, I have a request : does anyone know where this mosaic, what age , and other information ?
She is a very frequent contributor to many religious sites as an illustration to the " Parable of the Sower ," I'm probably 50 pieces found .
But never published anything about the mosaic.
I have to say that religious sites with rare scorn the authorship of works that place , for the most part they are not signed. As if the author is not important.
