The ins and outs of mythology are not always well understood. For example, Apollo Smintheus was 'mouse protector' but no one knows whether he protected the mice themselves or protected us from their ravages. Furthermore, few customes were followed universally, so that the implications of a custom followed in rural Greece might be contradicted by the implications of one from Etruria. It's enough to know that laurel was a symbol of honor and virginity but not necessarily both at the same time. Caaesar was granted the honor of wearing a laurel wreath whenever he pleased. Was ne a virgin? I think not.
