Following his adoption into the Antonine dynasty Severus could make some grand claims. No longer was he "avenger of the son of a freedman" he was now the son of the Divine Marcus and brother of the Divine Commodus. Who could deserve the throne more than a man who could trace his lineage back all the way to the Divine Nerva?
I mainly made this post to have a permanent record of an inscription I found displaying Severvs' new ancestry.

This inscription dates to 196AD and clearly shows the early stage of Severus' adoption agenda.
