Context paragraphs:
Julbocken (song): Julbocken, with the opening lines ""En jul när mor var liten"", is a Christmas song written by Alice Tegnér.  The lyrics describe a time when the "Julbocken" (Yule goat or Christmas goat) was still a more popular Christmas gift-bringer in Sweden than the "Jultomten" (Christmas elves or gnomes) or Santa Claus.  The lyrics describe the goat giving presents, a doll for "Mother" when she was a child, who was frightened when the goat jumped; and for her brother, a drum and a trumpet.  When the goat is old, he returns to "Mother", who now has children of her own.

Yule Goat: The Yule goat is a Scandinavian and Northern European Yule and Christmas symbol and tradition.  Its origin may be Germanic pagan and has existed in many variants during Scandinavian history.  Modern representations of the Yule goat are typically made of straw.

Christmas ham: A Christmas ham or Yule ham is a traditional dish associated with modern Christmas and historical Yule.  The tradition is believed to have begun among the Germanic peoples as a tribute to Freyr, a god in Germanic paganism associated with boars (see Sonargöltr), harvest and fertility.

Bukkehorn: A bukkehorn (Norwegian) or bockhorn (Swedish), also called ″Billy Goat Horn″ in English, is an ancient Scandinavian musical instrument, made from the horn of a ram or a goat.  The horn is usually made from a goat horn harvested 5 to 7 years before the instrument is crafted.  It was traditionally used by shepherds and milkmaids on summer dairy farms in the mountains, as a signal-instrument or as a scaring instrument.  When the horn later got finger holes it became possible to play melodies with it.  The instrument has two blowing-techniques: the trumpet-principle is the most common, but the clarinet-principle is also used.

Buz-baz: Buz- baz is a musical puppetry tradition found in northern Afghanistan.  The puppet is a goat which is controlled by a string connected to the wrist of the puppeteer.  The goat is completely carved out wood and made out of sequins and baubles and sometimes bells.  The goat stands for two things.  One is markhor, which means snake eating goat of Badakhshan, and the ancient belief that mountain goats had powers.

British Primitive goat: The British primitive goat is a landrace of domestic goat native to Great Britain and Ireland, and is the original goat of the region.  It is considered a rare breed, existing as several, isolated feral herds, as some captive populations in zoological parks and nature reserves, and breeding stock on some private farms operated by groups of rare-breed enthusiasts.  As few as 1,200 individual British primitives may remain.  The variety is also referred to as the British native goat, the old British goat, or the British landrace goat, among more specific names (English, Irish, Scottish or Scotch, and Welsh primitive or landrace goat, and old English, etc., goat).  It descends from the earliest goats brought to the region in the Neolithic era, around 3,000 BCE.  It is classified in the "Northern breed group" of goats.  A population in Northumbria is sometimes referred to as the Cheviot goat.  The British primitive is among the foundation stock of some modern standardised breeds, including the Anglo-Nubian goat.  The breed is comparatively small, with commensurately low milk production.  It is hardy and wiry haired, adapted to rough terrain and weather, and able to subsist and breed on its own without human intervention.

Yule log: The Yule log, Yule clog, or Christmas block is a specially selected log burnt on a hearth as a Christmas tradition in a number of countries in Europe.  The origin of the folk custom is unclear.  Numerous scholars have observed that, like other traditions associated with Yule (such as the Yule boar), the custom may ultimately derive from Germanic paganism.

Goat blanket: A goat blanket, or goat coat, is a blanket or coat covering intended to keep a domestic goat warm, or otherwise protected from the weather.  They can vary from simple fabric covers, to specially fitted garments which wrap securely around the body and neck, while still allowing the animal free movement.  Most goats develop a thick coat of fur in the fall months, but some types of goats do not, so need external protection.  Goat blankets can be made of various types of materials, including those modern materials used for human outdoor wear.  They can also be made in a variety of sizes to accommodate from young kids, to large adult goat species.

Gävle goat: The Gävle Goat (Swedish: "Gävlebocken" ) is a traditional Christmas display erected annually at Slottstorget (Castle Square) in central Gävle, Sweden.  It is a giant version of a traditional Swedish Yule Goat figure made of straw.  It is erected each year at the beginning of Advent over a period of two days by local community groups, and has become famous for being destroyed in arson attacks during December.  Despite security measures and the nearby presence of a fire station, the goat has been burned to the ground most years since its first appearance in 1966.  As of December 2016, the goat has been damaged 37 times.

Joulupukki: Joulupukki is a Finnish Christmas figure.  The name ""Joulupukki"" literally means "Christmas goat" or "Yule Goat" in Finnish; the word "pukki" comes from the Teutonic root "bock", which is a cognate of the English "buck", and means "billy-goat".  An old Scandinavian custom, the figure eventually became more or less conflated with Santa Claus.
