Ivy in the context of "Dryas (mythology)"

In Ancient Greece a thyrsus (/ˈθɜːrsəs/) or thyrsos (/ˈθɜːrsɒs/; Ancient Greek: θύρσος) was a wand or staff of giant fennel (Ferula communis) covered with ivy vines and leaves, sometimes wound with taeniae and topped with a pine cone, artichoke, fennel, or by a bunch of vine-leaves and grapes or ivy-leaves and berries, carried during Hellenic festivals and religious ceremonies. The thyrsus is typically associated with the Greek god Dionysus (and his subsequent Roman equivalent Bacchus) as a symbol of prosperity, fertility, and hedonism.

The cult of Dionysus consisted of devotees who involved themselves in forms of ecstatic worship in reverence of Dionysus. An ecstatic ritual performed by the cult included the orgeia, a forest rite involving ecstatic dance during the night. The Dionysia and Lenaia festivals in Athens were dedicated to Dionysus, as well as the phallic processions. These processions often featured villagers parading through the streets with large phallic representations. The cult of Dionysus traces back to at least Mycenaean Greece, since his name is found on Mycenean Linear B tablets as 𐀇𐀺𐀝𐀰 (di-wo-nu-so). However, many view Thrace and Phrygia as the birthplace of Dionysus, and therefore the concepts and rites attributed to his worship. Dionysian worship was especially fervent in Thrace and parts of Greece that were previously inhabited by Thracians, such as Phocis and Boeotia. Initiates worshipped him in the Dionysian Mysteries, which were comparable to and linked with the Orphic Mysteries, and may have influenced Gnosticism. It is possible that water divination was an important aspect of worship within the cult.

The cult was strongly associated with satyrs, centaurs, and sileni, and its characteristic symbols were the bull, the serpent, tigers/leopards, ivy, and wine. One reason for Dionysus's association with the silent is that Silenus, a chief figure among them, was said to have taught Dionysus the art of wine-making. Dionysus himself is often shown riding a leopard, wearing a leopard skin, or in a chariot drawn by panthers, and is also recognized by his iconic thyrsus. Besides the grapevine and its clashing alter-ego, the poisonous ivy plant, both sacred to him, the fig was another one of his accredited symbols. Additionally, the pinecone that topped his thyrsus linked him to Cybele, an Anatolian goddess. The Dionysian effect the god had on women also bores a resemblance to Krishna, an Indian god who enchanted female gopis with music to venture into the forest in the night.

Pith, or medulla, is a tissue in the stems of vascular plants. Pith is composed of soft, spongy parenchyma cells, which in some cases can store starch. In eudicotyledons, pith is located in the center of the stem. In monocotyledons, it extends only into roots. The pith is encircled by a ring of xylem; the xylem, in turn, is encircled by a ring of phloem.

While new pith growth is usually white or pale in color, as the tissue ages it commonly darkens to a deeper brown color. In trees pith is generally present in young growth, but in the trunk and older branches the pith often gets replaced – in great part – by xylem. In some plants, the pith in the middle of the stem may dry out and disintegrate, resulting in a hollow stem. A few plants, such as walnuts, have distinctive chambered pith with numerous short cavities. The cells in the peripheral parts of the pith may, in some plants, develop to be different from cells in the rest of the pith. This layer of cells is then called the perimedullary region of the pithamus. An example of this can be observed in Hedera helix, a species of ivy.

Messapian pottery is a type of Messapian ceramic, produced between the 7th century BC until the 3rd century BC on the Italian region of southern Apulia. Messapian pottery was made by the Messapii, an ancient people inhabiting the heel of Italy since around 1000 BC, who migrated from Crete and Illyria. Messapian pottery consisted first primarily, with geometric patterns like circles, squares, diamonds, horizontal dash patterns, swastika and other similar motifs. Late through Greek influence the meander was added. From about the beginning of the 5th century BC again under Greek influence, with imports of Attic pottery, figurative decoration was added. In addition, leaf motifs, new elements such as ivy and other repertoire were included. Up to then only fragments of the pottery was decorated in contrast to the whole surface being decorated after the 5th century BC. In the fourth century BC, the artists came back again to geometric ornamentation, but by then the ceramics were almost completely under Greek influence.

In botany, an umbel is an inflorescence that consists of a number of short flower stalks (called pedicels) that spread from a common point, somewhat like umbrella ribs. The word was coined in botanical usage in the 1590s, from Latin umbella "parasol, sunshade". The arrangement can vary from being flat-topped to almost spherical. Umbels can be simple or compound. The secondary umbels of compound umbels are known as umbellules or umbellets. A small umbel is called an umbellule. The arrangement of the inflorescence in umbels is referred to as umbellate, or occasionally subumbellate (almost umbellate).

Umbels are a characteristic of plants such as carrot, parsley, dill, and fennel in the family Apiaceae; ivy, Aralia and Fatsia in the family Araliaceae; and onion (Allium) in the family Alliaceae.
