'aurorean' originates from Latin, specifically the word 'aurora', where 'auror-' or 'aurora' meant 'dawn'.

'aurorean' developed via Late Latin/Medieval Latin formations such as 'auroreus' (formed from 'aurora' + adjectival suffix) and entered English usage as the adjective 'aurorean'.

Initially it meant 'of or pertaining to dawn', and over time it has retained that core sense, often with a poetic emphasis on dawn's rosy or golden color.
