Rough sketch:

Centennial developments and trends
Economy: Publicly funded inventions allow the mechanisation of cotton carding, dramatically increasing the availability of cotton textiles and reducing the required amount of labour.

Philosophy: Across universities in Gaul, the new "Celtic philosophy" spreads. It differs from Neoplatonism mainly in its epistemological foundation, which lays the ground for the later establishment of empirical sciences. Celtic philosophy also presents a major challenge for all revelatory religions.

Religion: Roman and Celtic polytheistic cult decline further, but Christianity does not gain all the ground, with new philosophical trends swelling the ranks of the non-religious. Christianity spreads across the Eastern coast of Africa aboard Aksumite and Saban merchant ships discovering new trading opportunities to the South.
