Wikipedia:Articles for deletion/Jan-Baptist Stella
I too can find no sources to establish this guy's existence, having tried Google Web and Books searches for the birth/death dates and for "Giovanni Battista Stella", which is a more likely form for the name of a Florentine painter. I don't know whether the article is a hoax, but it appears to fail
