Meaning

  1. adjectivered approximately like red ochre (which had a traditional status among the Romans); red that was both common and dignified, somewhat associated with pigment
    intereā fax / occidit Ōceanumque rubrā tractim obruit aethrāmeanwhile the torch (i.e., the sun) / goes down and buries the Ocean slowly with the red-lit sky239 BCE – 169 BCE, Ennius, Annales 16.416
    ager olētō cōnserundō, quī in uentum fauōnium spectābit et sōlī ostentus erit: alius bonus nūllus erit. quī ager frīgidior et macrior erit, ibi oleam liciniānam serī oportet; sīn in locō crassō aut calidō sēueris, hostus nēquam erit et ferundō arbor perībit et muscus ruber molestus erit.The land for planting an olive-grove on it is that which is facing the west wind and gets sun. No other will be good. If you have land that is rather cold and dry, then the Licinian olive should be planted there; else if you plant it in a wet or a warm place, the olive yield will be wretched and the tree will die giving this yield, and there will be red moss that causes trouble.234 BCE – 149 BCE, Marcus Porcius Cato, De agri cultura 6.2.6
