No, the succession (Sanskrit, Greek, Latin, post-Latin) was given mainly in terms of the apogee - one peak follows the other in time. When I wrote «Sanskrit entered into Greek, Greek into Latin, Latin into English» I described the phenomenon, not the fact.

The literal matter (of direct inheritance) was meaningless to me in the composition, because the whole point was not and is not "what took from what": the whole point is the contribution that those languages give in the understanding of the current languages they informed.
