It is a characteristic of a certain kind of academic writing (or amateurish misconceptions thereof) to join prepositions by conjunctions with only one object. Some examples:
The realization of the good of all in and through the act of each is the social ideal. (Practical Ethics, William DeWitt Hyde)
Or the common idiom: "in and of itself".
Are there any examples in classical literature of two prepositions being joined by a conjunction with the same object?
Obviously, I am not interested in cases like "per ipsum, et cum ipso, et in ipso."
A word search for "in et" (with word boundaries) shows only result where "in" is treated as a noun, i.e. "the word in."
