Demiurge, the world builder, the mythical god of creation in Plato's dialogue Timaios. The demiurge created the physical world, not out of nothing, but by bringing order to chaos with the eternal (reason, ideas) as a model.

The word demiurge comes from Greek demiurgos meaning 'craftsman', but actually meaning 'working for the people', since demos means 'people' and ergon means ‘work'.
