CHRIST vs KRISHNA: Re-Reading Sakes in Historic Context

Way back in the year 2005 when we met in New York at the First International Conference on Early Christianity in India the scholarship that were present felt that we have discovered the secret of the history after a long period of research into the history of the Language of Sanskrit and the history of the religion today known as Hinduism. My study in this area appeared in the Souvenir of the Conference which I thought was a ground breaking work and was wondering how with all the historic realities and documentary and archeological evidences why no one else thought about this earlier. So when I stumbled on the Christ vs., Krishna by Sakes written over 120 years ago I was clean flabbergasted. How could such a clear understanding of realities remained hidden to the scholarship for such a long time?
