Cad Goddeu (Middle Welsh: Kat Godeu, English: "The Battle of the Trees") is a medieval Welsh poem preserved in the 14th-century manuscript known as the Book of Taliesin. The poem refers to a traditional story in which the legendary enchanter Gwydion animates the trees of the forest to fight as his army. The poem is especially notable for its striking and enigmatic symbolism and the wide variety of interpretations this has occasioned.
Some 248 short lines long (usually five syllables and a rest), and falling into several sections, the poem begins with an extended claim of first-hand knowledge of all things, in a fashion found later in the poem and also in several others attributed to Taliesin;
Bum cledyf yn aghat
Bum yscwyt yg kat
Bum tant yn telyn.
I was a sword in hand
I was a shield in battle
I was a string on a harp.
culminating in a claim to have been at "Caer Vevenir" when the Lord of Britain did battle. There follows an account of a great monstrous beast, of the fear of the Britons and how, by Gwydion's skill and the grace of God, the trees marched to battle: then follows a list of plants, each with some outstanding attribute, now apt, now obscure;
Gwern blaen llin,
A want gysseuin
Helyc a cherdin
Buant hwyr yr vydin.
Alder, front of the line,
formed the vanguard
Willow and Rowan
were late to the fray.
The poem then breaks into a first-person account of the birth of the flower-maiden Blodeuwedd, and then the history of another one, a great warrior, once a herdsman, now a learned traveller, perhaps Arthur or Taliesin himself. After repeating an earlier reference to the Flood, the Crucifixion and the day of judgment, the poem closes with an obscure reference to metalwork.
There are contemporary passing allusions to the Battle of Trees elsewhere in the medieval Welsh collections: The Welsh Triads record it as a "frivolous" battle, while in another poem of the Book of Taliesin the poet claims to have been present at the battle.
According to a summary of a similar story preserved in Peniarth MS 98B (which dates from the late sixteenth century) the poem describes a battle between Gwydion and Arawn, the Lord of Annwn. The fight broke out after the divine plowman Amaethon stole a dog, a lapwing, and a roebuck from Arawn. Gwydion ultimately triumphed by guessing the name of one of Arawn's men, Bran (possibly Bran the Blessed).
In the Mabinogi story of the childhood of Lleu Llaw Gyffes, Gwydion makes a forest appear to be an invading force.
The Cad Goddeu, which is difficult to translate because of its laconic allusiveness and grammatical ambiguity, was the subject of several nineteenth-century speculative commentaries and English renderings. Thomas Stephens held the poem to concern "a Helio-Arkite superstition, the metempsychosis of a Chief Druid, and a symbolical account of the Deluge".[1] Gerald Massey's monumental work on African origins suggested that the poem reflected Egyptian religion.[2]
David William Nash believed it was a poor-quality twelfth-century romance overlaying a romance or story of the Arthurian era and put together with other poetic fragments.[3] W. F. Skene rejected the antiquity of the prose account and thought the poem reflected the history of the north country during the Irish incursions.[4] Watson followed Skene and Ifor Williams posed the question 'What about the Battle of Celyddon Wood?'
Robert Graves took up a speculation that had been considered and rejected by Nash; that the trees that fought in the battle correspond to the Ogham alphabet, in which each character is associated with a particular tree. Each tree had a meaning and significance of its own, and Gwydion guessed Bran's name by the alder branch Bran carried, the alder being one of Bran's prime symbols. Graves argued that the original poet had concealed druidic secrets about an older matriarchal Celtic religion for fear of censure from Christian authorities. He suggested that Arawn and Bran were names for the same underworld god and that the battle was probably not physical but rather a struggle of wits and scholarship: Gwydion's forces could only be defeated if the name of his companion, Lady Achren ("Trees"), was guessed and Arawn's host only if Bran's name was guessed.
Graves, following Nash, accepted that the poem is a composite of several different sections, among which he named a Hanes Taliesin (History of Taliesin) and a Hanes Blodeuwedd (History of Blodeuwedd).
Marged Haycock and Mary Ann Constantine reject the idea that Cad Goddeu encodes ancient pagan religions as Graves believed but rather see it as a burlesque, a grand parody of bardic language. Francesco Bennozo argues that the poem represents ancient fears of the forest and its magical powers. Trudy Carmany Last suggests that Cad Goddeu is a Celtic variant of Virgil’s Aeneid.[5]
A track titled "Cad Goddeau" appears on the 1984 album Eostre by the British band Zoviet France.
Singer-songwriter Tori Amos was inspired by the story of Cad Goddeu for her song "Battle of Trees", which appears on Night of Hunters, a narrative concept album, presented as a 21st-century song cycle. This song, a variation on Erik Satie's Gnossienne No. 1,[6] uses references to Cad Goddeu to reflect on the power of language as a battle-ready weapon.[7]
Soviet and later Russian rock group Aquarium recorded a song "Kad Goddo" on their album Deti Dekabrya, 1986, quoting some of the lines directly from the poem.
Tim Powers has the protagonist of his book The Drawing of the Dark, Brian Duffy, utter a few verses of the Cad Goddeu to evoke ancient beings to fight with him.[8]
"Duel of the Fates" is a musical theme recurring in the Star Wars prequel trilogy and the expanded universe. It was composed by John Williams and recorded for the film soundtrack by the London Symphony Orchestra and the London Voices. This symphonic piece is played with both a full orchestra and a choir. The lyrics are based on a fragment of Cad Goddeu, and sung in Sanskrit.[9]

CAD/CAM refers to the integration of computer-aided design (CAD) and computer-aided manufacturing (CAM). Both of these require powerful computers. CAD software helps designers and draftsmen; CAM "reduces manpower costs" in the manufacturing process.
BRL-CAD is a constructive solid geometry (CSG) solid modeling computer-aided design (CAD) system. It includes an interactive geometry editor, ray tracing support for graphics rendering and geometric analysis, computer network distributed framebuffer support, scripting, image-processing and signal-processing tools. The entire package is distributed in source code and binary form. Although BRL-CAD can be used for a variety of engineering and graphics applications, the package's primary purpose continues to be the support of ballistic and electromagnetic analyses. In keeping with the Unix philosophy of developing independent tools to perform single, specific tasks and then linking the tools together in a package, BRL-CAD is basically a collection of libraries, tools, and utilities that work together to create, raytrace, and interrogate geometry and manipulate files and data. In contrast to many other 3D modelling applications, BRL-CAD primarily uses CSG rather than boundary representation. This means BRL-CAD can "study physical phenomena such as ballistic penetration and thermal, radiative, neutron, and other types of transport". It does also support boundary representation. The BRL-CAD libraries are designed primarily for the geometric modeler who also wants to tinker with software and design custom tools. Each library is designed for a specific purpose: creating, editing, and ray tracing geometry, and image handling. The application side of BRL-CAD also offers a number of tools and utilities that are primarily concerned with geometric conversion, interrogation, image format conversion, and command-line-oriented image manipulation.
CAD/CAM dentistry is a field of dentistry and prosthodontics using CAD/CAM (computer-aided-design and computer-aided-manufacturing) to improve the design and creation of dental restorations, especially dental prostheses, including crowns, crown lays, veneers, inlays and onlays, fixed dental prostheses (bridges), dental implant supported restorations, dentures (removable or fixed), and orthodontic appliances. CAD/CAM technology allows the delivery of a well-fitting, aesthetic, and a durable prostheses for the patient. CAD/CAM complements earlier technologies used for these purposes by any combination of increasing the speed of design and creation; increasing the convenience or simplicity of the design, creation, and insertion processes; and making possible restorations and appliances that otherwise would have been infeasible. Other goals include reducing unit cost and making affordable restorations and appliances that otherwise would have been prohibitively expensive. However, to date, chairside CAD/CAM often involves extra time on the part of the dentist, and the fee is often at least two times higher than for conventional restorative treatments using lab services. Like other CAD/CAM fields, CAD/CAM dentistry uses subtractive processes (such as CNC milling) and additive processes (such as 3D printing) to produce physical instances from 3D models. Some mentions of "CAD/CAM" and "milling technology" in dental technology have loosely treated those two terms as if they were interchangeable, largely because before the 2010s, most CAD/CAM-directed manufacturing was CNC cutting, not additive manufacturing, so CAD/CAM and CNC were commonly used together; but whereas this loose/imprecise usage was once somewhat close to accurate, it no longer is, as the term "CAD/CAM" does not specify the method of production except that whatever method is used takes input from CAD/CAM, and today additive and subtractive methods are both widely used.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
