There's a Latin poem which contains the line militis in galea meaning, literally, 'of the soldier - in - helmet' or, more colloquially, in the soldier's helmet. In this case the preposition is stuck between the two nouns that we would think would go together. In Latin you can put the words in whatever order to represent the importance of a given word to your thought or, in the case of poetry, to make a more mellifluous sound.
