Yeah, the level titles were something seemingly taken from a thesaurus.
In Chainmail, it was Seer, Magician, Warlock, Sorcerer, Wizard
In OD&D, it was Medium, Seer, Conjurer, Theurgist, Thaumaturgist, Magician, Enchanter, Warlock, Sorcerer, Necromancer, Wizard
In AD&D 1e it was Prestidigitator, Evoker, Conjurer, Theurgist, Thaumaturgist, Magician, Enchanter, Warlock, Sorcerer, Necromancer, Wizard, and then at 18th level Arch-Mage
From Oe to 1e you can see an attempt to change the first two from a more spiritualist theme to magic, even if Prestidigitator is more state magic
