The Álfablót or the Elven sacrifice was a pagan Scandinavian sacrifice to the elves towards the end of autumn, when the crops had been harvested and the animals were most fat.
 Unlike the great blóts at Uppsala and Mære, the álfablót was a local celebration at the homesteads and they were mainly administered by the lady of the household.
 Nothing is known about the particular rites because they were surrounded by secrecy and strangers were not welcome to the homesteads during the celebrations.
 However, since the elves were collective powers with a close connection to ancestors and fertility, it is possible that the álfablót concerned ancestor worship and the life force of the family.
 It also appears that Odin was implied and that the master of the household was called "Ölvir" when administering the rites.
 The first element of "Ölvir" means "beer", which was an important element in Norse pagan sacrifices generally.
Jig dolls are traditional wooden or tin-plate 'toys' for adults or children.
 They are dolls with loose limbs that step dance or 'jig' on the end of a vibrating board or platform in imitation of a real step dancer.
 In London they were frequently operated by street entertainers or buskers.
 In England old soldiers from the Great War sometimes busked with them to supplement their meagre war pensions.
 Typically the dolls are between 20–30 cm tall and are jointed at arms, hips and knees; some also have ankle joints.
 Today, jig dolls of one kind or another can be seen in the USA, Canada, the UK, Ireland, Europe, parts of Asia, and Australia.
Punta is a Garifuna music and dance style performed at celebrations and festive occasions.
 (Garifuna music and dance was created by the Garifuna people of present-day St. Vincent and Dominica.)
Step dance is the generic term for dance styles in which the footwork is the most important part of the dance.
 Limb movements and styling are either restricted or considered irrelevant.
