One of Hadrian's immediate duties on accession was to seek senatorial consent for the apotheosis of his predecessor, Trajan, and any members of Trajan's family to whom he owed a debt of gratitude. Matidia Augusta, Hadrian's mother-in-law, died in December 119, and was duly deified. Hadrian may have stopped at Nemausus during his return from Britannia, to oversee the completion or foundation of a basilica dedicated to his patroness Plotina. She had recently died in Rome and had been deified at Hadrian's request.
