In Greek mythology, a centaur (from Ancient Greek: Κένταυροι – Kéntauroi) or hippocentaur is a member of a composite race of creatures, part human and part horse. In early Attic and Boeotian vase-paintings, they are depicted with the hindquarters of a horse attached to them; in later renderings centaurs are given the torso of a human joined at the waist to the horse's withers, where the horse's neck would be.
This half-human and half-animal composition has led many writers to treat them as liminal beings, caught between the two natures, embodied in contrasted myths, both as the embodiment of untamed nature, as in their battle with the Lapiths, or conversely as teachers, like Chiron.
The centaurs were usually said to have been born of Ixion and Nephele (the cloud made in the image of Hera). Another version, however, makes them children of a certain Centaurus, who mated with the Magnesian mares. This Centaurus was either himself the son of Ixion and Nephele (inserting an additional generation) or of Apollo and Stilbe, daughter of the river god Peneus. In the later version of the story his twin brother was Lapithus, ancestor of the Lapiths, thus making the two warring peoples cousins. (more on Wikipedia)
Thor, the norse god of thunders welding the magic hammer Mjölnir (el-grimlock)
In Norse mythology, Thor (from Old Norse Þórr) is a hammer-wielding god associated with thunder, lightning, storms, oak trees, strength, the protection of mankind, and also hallowing, healing, and fertility. The cognate deity in wider Germanic mythology and paganism was known in Old English as Þunor and in Old High German as Donar (runic þonar ᚦᛟᚾᚨᚱ), stemming from a Common Germanic *Þunraz (meaning "thunder").
Ultimately stemming from Proto-Indo-European religion, Thor is a prominently mentioned god throughout the recorded history of the Germanic peoples, from the Roman occupation of regions of Germania, to the tribal expansions of the Migration Period, to his high popularity during the Viking Age, when, in the face of the process of the Christianization of Scandinavia, emblems of his hammer, Mjölnir, were worn in defiance and Norse pagan personal names containing the name of the god bear witness to his popularity. Into the modern period, Thor continued to be acknowledged in rural folklore throughout Germanic regions. Thor is frequently referred to in place names, the day of the week Thursday ("Thor's day") bears his name, and names stemming from the pagan period containing his own continue to be used today.
