Prolog was not intended to be an object-oriented language. The first sentence of C&M uses the word "object", but in preference to a word like "thing". Remember it was written before the term "object-oriented" came into common use, and there was no way to predict whether this might cause confusion in the future. Given that the remainder of the book does not mention any of the concepts used by the object-oriented languages, it would be very surprising indeed if anyone were to be misled by the use of the word "object" in the first sentence.
