Scheme is the common dialect of many implementation projects, and is specified in English. Some of those Scheme implementations use C, some do not.
Scheme implementations are not all smaller and simpler than Clojure as a whole. Of course they have a lot more content than just the core specified in the Scheme report.
Gauche Scheme has a reference manual of over 1000 pages, for instance.
Racket can be counted as a Scheme implementation; it is also large.
There is a list of Scheme implementations in the Wikipedia:
