Context paragraphs:
Halizones: The Halizones (Greek Ἁλιζῶνες, also Halizonians, Alizones or Alazones) are an obscure people that appear in Homer's Iliad as allies of Troy during the Trojan War.  Their leaders were Odius and Epistrophus, said in the "Bibliotheca" to be sons of a man named Mecisteus.  According to Homer, the Halizones came from "Alybe far away, where is the birth-place of silver..." Strabo (in his "Geography") speculates that "Alybe far away" may originally have read as "Chalybe far away", and he suggests that the Halizones may have been Chalybes, as well as Khaldi.  Strabo's speculation equating the Halizones with the Chalybes still has proponents, such as the Soviet historian, Igor Diakonoff.

Walter Poenisch: Walter Poenisch (July 11, 1913 - June 6, 2000) was an American baker and long-distance swimmer.  In 1963, at the age of 50, Poenisch began his professional swimming career by swimming in the Jim Moran Lake Michigan Swim, a 30-mile professional marathon swim in Lake Michigan.  In June 1972, Poenisch tried to establish a long-distance ocean swimming record off of Florida but was pulled from the water after sharks attacked his safety cage.  In 1976, he swam 125 miles in the Florida Straits and was listed in the Guinness Book of World Records for the longest ocean swim.  To memorialize his 65th birthday in 1978, Poenisch set out to be the first to swim from Havana, Cuba to the Florida Keys.  As then-President of Cuba Fidel Castro watched, Poenisch began his swim from Cuba on July 13, 1978.  About thirty-three hours later, Poenisch arrived at Little Duck Key, a small island in the lower Florida Keys.  As a result of not filing for official recognition - he had no outside observer beside his own personal crew - his swim did not receive official recognition.  He subsequently sued three parties, including the International Swimming Hall of Fame and Diana Nyad, a long-distance swimmer competitor who began her first Cuba-to-Florida swim on July 16, 1978 - two days after Poenisch arrived in Florida.  Poenisch claimed that Nyad's publicist and Nyad had slandered him just before she left on her swim due to how they characterized his Cuba-to-Florida swim efforts.  Poenisch received $5,000 from each of the three parties in an out-of-court settlement five years later in April 1983.  Poenisch died in June 2000 and, as of September 2013, has not received official recognition for his 1978 Cuba-to-Florida swim.
