4. Two 1 st century Roman works mention Tiberius, protogreenhouse, and cucurbits Luciuis Junius Mereratus Columella De Re Rustica (On Agriculture) Gaius Plinius Secundus (Pliny the Elder) Historia Naturalis (Natural History)

5. Columella Anyone who wishes to have the fruits of cucumis ripe earlier than usual should, when midwinter is past, produced well-manured soil enclosed in baskets and give it a moderate amount of water; then, when the seeds have come up, he should place the baskets in the open air on warm and sunny days near a building, so that they may be protected from any blasts of wind; but if it be cold and stormy, he should bring them back under cover and continue to do so until the spring equinox is over. He should then sink the whole baskets into the ground. He will thus have early fruits. Is also possible, if it be worth the trouble, for wheels to be put under larger vessels, so that they may be brought out and taken indoors again with less labour. In any case the vessels ought to be covered with specularibus so that even in cold weather, when the days are clear, they be safely be brought out into the sun. By this method Tiberius Caesar was supplied with cucumis during almost the whole year. (11, 3, 52–53)

6. Pliny Cucumis was a delicacy for which the emperor Tiberius had a remarkable partiality: in fact there was never a day on which he was not supplied with it, as his kitchen gardeners had cucumis beds mounted on wheels which they moved out into the sun and then on wintry days withdrew under the cover of frames glazed with transparent stone (mica). (19, 23, 64)

8. What is cucumis referred to by both Columella and Pliny? Cucumis generally translated as cucumber Gerard 1597 Ash 1941 (Columella translator) Jones 1951 (Pliny translator) Whitaker and Davis 1962 Kirkbride 1993 Robinson and Decker Walters 1997 Jeffrey 2001

9. Pliny refers to cucumis and cucurbita as: Cartilagenous (pliable) fruits Normally prostrate on the ground but could also climb Cucumis composed of cartilage (pliable skin) and flesh Cucurbita composed of cartilage and rind which becomes woody when ripened

10. Cucumis describes various types of “melon” (Citrullus, Cucumis, Ecballium) Columella Twisted Bluish with swollen womb, hairy Snake like Foul juice Whitish, turns yellow when ripe

11. Chate melon (Vesling 1640) Chate melon ‘Carosello Barese’ (top) and Bet Alfa-type cucumber ‘Shimshon’ (bottom)

12. Cucumber ‘Shimshon’ (left) and snake melon ‘Striped Snake’ (right)

13. Pliny Vary when grown in different regions Grow into any shaper forced to take Blossoms covered with white down Round (quince-like) forms in Campania, & fruit separates from stalk when ripe, aromatic Very large ones in Moesia called pepones (watermelon = Citrullus) Wild cucumis is a source of elaterium (squirting cucumber = Ecballium elaterium) Wild cucumis called colocynthi (Colocynth = Citrullis colocynthis)

14. Cucurbita describes bottle gourd (Lagenaria) Columella Swelling Sometimes hang from arbors Sometimes snake-like If you want long ones, select seed from the neck If you want globular ones, choose seed from midbelly Use for vessels, water pails, wine flask, or floats for teaching boys to swim Pliny Long ones used for culinary purposes Seeds nearest the neck produce long gourds

15. An accurate understanding of the history and development of food plants requires critical evaluation and comparison of widely interdisciplinary evidence from horticulture botany, archaeology, history, and philology (Dalby 2003) Plant iconography has played the most important role in the accurate identification of cucurbit taxa in the Renaissance (Eisendrath 1961) especially with regard to the American genus Cucurbita (Paris 2001). Although, detailed depictions and accurate descriptions of cucurbits are much scarcer in medieval times and antiquity they are scattered but they exist.

37. Conclusions The cucumis beloved by Tiberius appears to be Cucumis melo Flexuosus Group and not cucumber based on: 1.Descriptions of cucumis in Columella and Pliny excludes cucumber (snake-like, hairy). 2.The tubercules common on the fruit which would have been noticed are not mentioned. 3.Absence of any cucumber images in antiquity. 4.First images of cucumber are found in 1335 suggesting cucumber arriving late in Europe probably with mogul invasions of the west beginning with Genghis Khan. 5.Subsequent images of cucumber in the West are very similar indicating the introduction of one specific type. The mistranslation of cucumis for cucumber is probably due to the similarity of its name with cucumis and cucurbita.
