I see. Well, no, the "oldest attestation of a mango" isn't found in the Vedas. A mango is mentioned in passing in an Upanishad. I'm not sure how notable this is to the mango article. As to "above and over all fruits", I don't know which text you are referring to. I am sure there are lots of stories involving mangoes in medieval Indian texts, but I haven't researched these.  (𒁳)
