Exaltationes would be Latin. When it's at the beginning of a letter, it's usually as we say, "your eminence" or "your highness" in English. "Oh most exalted one"—the salutation to someone important.
In a general sense, it refers to something "up there" (high, overhead, of greater importance, exalted, or a prominent person).
