ruins or at fountains and ponds, where they comb their hair. Other times, they are gigantic women of incredible strength, enough to move massive boulders, who can be found with a spinning distaff or a baby. Under this appearance they are the same with the Vella ("the Old Lady"), who is somehow also responsible for the weather: the rainbow is called arco da vella in Galician ("Old Lady's bow"), a myth which is probably related to the Cailleach, 'Old Woman', 'Hag', of Ireland and Scotland. Lavandeiras (washerwomen) are eerie fairies that are found at a river of pond washing clothes, under the aspect of women, especially at night. They can ask a passer-by to help twits the clothes: if the passer-by mistakenly twists in the same direction, the clothes turn into blood. The trasnos, tardos or trasgos (goblins) are mischievous, household creatures, who like to annoy and confound people. They can cause nightmares by siting on the chest of the people, move things and cause other troubles. In Galician trasnada (~'goblin-ery') means 'trick, mischief'. Other sign of the netherworld is the apparition of a golden hen followed by his golden chicks (a galiña dos pitos de ouro), which, no matter how hard one tries, can't be caught. There is a similar myth in Bulgaria. Maruxaina was a vicious siren who lived near the town of San Cribrao and who eventually was captured and executed by the locals. The barrows are also inhabited by other entities called ouvas ('elfs'). Other beings with control of the weather are the nubeiros ('cloud-ers'). George Borrow in his book The Bible in Spain narrates how he met a nubeiro while travelling Galicia circa 1835. Other similar beings are the tronantes and escoleres. Many lakes are believed to be the result of the drowning of ancient cities (frequently called Lucerna, Valverde, 'Green Valley', or Antiochia in tales and legends) when the inhabitants failed to give shelter to Jesus or a saint, or when a king of the mouros used his magic out of spit. Some nights the city's bells can still be heard. This legend was first recorded in the 12th century Codex Calixtinus and in that version is Charlemagne who prays God and Saint James to drown a Moor city reluctant to commit to him. This myth appear to be related to the Breton myth of Ys. Another mythical being associated with drowned cities is
