They have no agriculture, no wine, and live on milk, cheese and the meat of sheep. They live solitary lives, and have no government. They are inhospitable to strangers, slaughtering and eating all who come to their land. While Homer does not say if the other Cyclopes are like Polyphemus in their appearance and parentage, Euripides makes it explicit, calling the Cyclopes "Poseidons one-eyed sons". And while Homer is vague as to their location, Euripides locates the land of the Cyclopes on the island of Sicily near Mount Etna.Like Euripides, Virgil has the Cyclopes of Polyphemus live on Sicily near Etna. For Virgil apparently, these Homeric Cyclopes are members of the same race of Cyclopes as Hesiods Brontes and Steropes, who live nearby. Cyclopean wall-builders
Cyclopes were also said to have been the builders of the so-called Cyclopean walls of Mycenae, Tiryns, and Argos. Although they can be seen as being distinct, the Cyclopean wall-builders share several features with the Hesiodic Cyclopes: both groups are craftsmen of supernatural skill, possessing enormous strength, who lived in primordial times. These builder Cyclopes were apparently used to explain the construction of the stupendous walls at Mycenae and Tiryns, composed of massive stones that seemed too large and heavy to have been moved by ordinary men.These master builders were famous in antiquity from at least the fifth century BC onwards. The poet Pindar has Heracles driving the cattle of Geryon through the "Cyclopean portal" of the Tirynian king Eurystheus.
Impact in the United States
M. cerebralis was first recorded in North America in 1956 in Pennsylvania, having been introduced via infected trout imported from Europe, and has spread steadily south and westwards. Until the 1990s, whirling disease was considered a manageable problem affecting rainbow trout in hatcheries. However, it has recently become established in natural waters of the Rocky Mountain states (Colorado, Wyoming, Utah, Montana, Idaho, New Mexico), where it is causing heavy mortalities in several sportfishing rivers. Some streams in the western United States have lost 90% of their trout. In addition, whirling disease threatens recreational fishing, which is important for the tourism industry, a key component of the economies of some U.S. western states. For example, "the Montana Whirling Disease Task Force estimated trout fishing generated US $300,000,000 in recreational expenditures in Montana alone". Making matters worse, some of the fish species that M. cerebralis infects (bull trout, cutthroat trout, and steelhead) are already threatened or endangered, and the parasite could worsen their already precarious situations. For reasons that are poorly understood, but probably have to do with environmental conditions, the impact on infected fish has been greatest in Colorado and Montana, and least in California, Michigan, and New York. Impact in Canada
Whirling disease was first detected in fish in Johnson Lake in Banff National Park in May, 2016. CFIA Labs confirmed in August and Parks Canada announced the outbreak August 23, 2016. Although it was first discovered in Banff, it is not necessarily where the disease originated and spread.
