Last time, we saw that Lunes and Monday are from the same God, the moon. Now we will see the same for Martes and Tuesday.
Martes, the Spanish for Tuesday, is named after the Roman God of War, whom we all learned about in middle school mythology classes: Mars.
Tuesday is named after Tiw, who was the Germanic God of War — their equivalent of Mars!
Tuesday is thus, literally, “Tiw’s Day”.
More interestingly, the name “Tiw” comes from the Indo-European Root “Dye-us” (think of the T-iw and D-ye parallel with the final “-us” being lost) — from which we also get the Spanish word dios (for God) and the Sanskrit deva (we all know that that means!).
