   Synonym: lūmen

   • 405 CE, Jerome, Vulgate Genesis.1.3:

     sī sēcrēta magis dūcis in antra, sequor.’

     If ever some young man spoke to this [nymph] the words of love, immediately she replied with statements such as: “These places have too much of daylight and, with the light, [too much] of shame; if you lead to more secluded caves, I [will] follow [you].”
