As stated in this question:
The Latin names for the days of the week used to be all named for the planets of Hellenistic astrology:
dies Solis (Sol) dies Lunae (Luna) dies Martis (Mars) dies Mercurii (Mercury) dies Jovis (Jupiter) dies Veneris (Venus) dies Saturni (Saturn)
The influence of Catholicism and its own Ecclesiastical Latin names for the weekdays had the effect of changing the weekend names to sábado (sabbatum) and domingo (dies Dominicus/Dominica) in Spanish (and to similar ones in all other romance languages, save for the surviving De Sadorn in Corsican).
Is there any record of intermediary forms being used between the Late Latin dies Saturni, dies Solis and modern Spanish sábado, domingo? E.g:
- [dies] Saturni > *satorne(s) > *sadornes
- [dies] Solis > *soles
