rubeus (feminine rubea, neuter rubeum); first/second-declension adjective

1. red, reddish (colour)
   • 37 BCE, Marcus Terentius Varro, De Re Rustica, book 2, chapter 8:

     [Bōvum sit] corium tactū nōn asperum ac dūrum, colōre potissimum nigrō, deinde robeō, tertiō helvō, quartō albō[...]

     [Cows'] skin [should be] not rough and hard to the touch, with a color preferably black, next red, third yellow, fourth white[...]

   • (Can we date this quote?), Gaius Julius Hyginus, “Polyidus”, in Fabulae‎:

     Mīnos sorte audītā coepit mōnstrum ā suīs quaerere; cui dīxērunt nātum esse uītulum quī ter in diē colōrem mūtāret per quaternās hōrās, prīmum album, secundō rubeum, deinde nigrum. Minos autem ad mōnstrum solvendum augurēs convocāvit, quī cum nōn invenīrentur, Polyīdus Coeranī fīlius Bizantī mōnstrum dēmōnstrāvit, eum arborī mōrō similem esse; nam prīmum album est, deinde rubrum, cum permātūrāvit nigrum.

     Minos, having heard the oracle, began to seek a monster from among his people; they said that to them had been born a calf that would change its color three times a day every four hours, first white, second red, then black. So Minos called the augurs together to deal with the monster; when they were not found, Polyidus, son of Coeranus of Byzantium, pointed out that the monster was similar to the blackberry tree, for it is first white, then red, and when it has entirely ripened, black.

   • c. 400, Rutilius Taurus Aemilianus Palladius, Opus Agriculturae‎, book 4 (Mensis Martius), chapter 14 (De mulis et asinis), line 3:

     Admissārius tamen asinus sit huiusmodī, corpore amplō, solidō, mūsculōsō, strictīs et fortibus membrīs, nigrī vel mūrīnī maximē colōris aut rubeī: quī tamen, sī discolōrēs pilōs in palpebrīs aut auribus geret, colōrem subolis plērumque variābit.

     But a stud donkey should be of this kind: with a large, firm, muscular body, tight and strong limbs, of a black, or at most mouse-like or red, color; but if it has different-colored hairs on its eyelids or ears, then it will mostly make its offspring's color different.

First/second-declension adjective.

• (red): ruber, russus

From rubus (“bramble bush”) +‎ -eus.

rubeus (feminine rubea, neuter rubeum); first/second-declension adjective

1. of or pertaining to the bramble or blackberry bush
   • 29 BCE, P. Vergilius Maro, Georgics‎, book 1, lines 264-7:

     Exacuunt aliī vallōs furcāsque bicornīs
     atque Amerīna parant lentae retinācula vītī.
     Nunc facilis rubeā texātur fiscina virgā,
     nunc torrēte ignī frūgēs, nunc frangite saxō.

     Others sharpen the stakes and two-horned forks
     and prepare the Amerian trellises for the flexible grapevine.
     Now let the easily-made basket be woven of blackberry twigs;
     now dry the fruits with fire, now break them with stone.

First/second-declension adjective.
