He served in this capacity for a total of six years between 1654 and 1662, and then served as deputy for 12 years from 1664 to 1690.  During the years when he wasn't serving as deputy, he was an assistant, serving in this role for a total of ten years.

It has a few good scenes, but is essentially "roman à clef" nonsense that every writer has to get out of his system early on.  Do yourself a favor and read ANYTHING else I've written (you'll be doing me a favor, too).  Forgive the follies of youth."
