Textual evidence: Plutarch on Roman head covering customs

Plutarch (first-century Roman biographer) asks why sons cover heads at funerals but daughters go bareheaded with hair unbound. He speculates this may reverse normal custom, implying normal practice was: women go covered in public, men go uncovered. At funerals, the practice is reversed for mourning. Plutarch also notes religious head covering practices: Romans covered heads when worshiping gods.
