This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Tartalo (Basque)
Tartaro, Tartalo, or Torto in Basque mythology, is an enormously strong one-eyed giant very similar to the Greek Cyclops that Odysseus faced in Homer's Odyssey. He is said to live in caves in the mountains and catches young people in order to eat them; in some accounts he eats sheep also.
Tartaro has been described as the Basque equivalent to the cyclops Polyphemus, and similarity to this cyclops in Homer's Odyssey is compelling, however direct derivation from Homeric sources may not be necessarily involved, since parallels to these can be found worldwide.
