Harishena, minister and poet of Samudragupta, carved a long Sanskrit eulogy of his king onto a pillar that already bore Ashoka’s edicts.

What it says

It lists the kings of Aryavarta whom Samudragupta uprooted, the twelve kings of Dakshinapatha, among them Vishnugopa of Kanchi, whom he captured and then set free, and the frontier kingdoms (Samatata, Kamarupa, Nepala and others) that paid tribute. It praises him as a poet and a musician. Jahangir later added his own genealogy to the same shaft.

What it proves

It is the main source for the extent of Samudragupta’s conquests and the shape of the early Gupta empire.
