Proselytizing activity?

In a comment to a posting of mine below Mike Bird asks if Could you guys blog on Philo's witness to Jewish missionary activity in the Diaspora? It is something that has interested me. In short, does Philo attest Jewish proselytizing activity amongst Gentiles. Several monographs have touched upon this (McKnight, Feldman, Goodman and recently John P. Dickson). On my part, this is problematic; on the one hand, I don't think there is much to go by in the work of Philo; on the other hand, as I am for the time being living away from my main library, I don't have the relevant books available (such as e.g., McKnights book). There is much about proselytism in the works of Philo, but I don't think one will find much about 'proselytizing activities', whatever these might be defined.

If any others readers, however, co-blogger Kåre or others, would like to throw in some pennies here, please use the comments field below. It might get something started.
