Pollux (mountain)

Pollux (4,092 m) is a mountain in the Pennine Alps on the border between Valais, Switzerland and the Aosta Valley in Italy. It is the lower of a pair of twin peaks (Zwillinge), the other being Castor, named after the Gemini twins of Roman mythology. It is separated from Castor by a pass at 3,845 m (12,615 ft), named the Passo di Verra in Italian and the Zwillingsjoch in German. The peak is known as Monte Polluce in Italian.

The first ascent was by Jules Jacot from Geneva with guides Josef-Marie Perren and Peter Taugwalder (father) on August 1 (the Swiss national day) 1864. Their route was via the Schwartztor, a pass first crossed by John Ball and Gabriel Zumtaugwald in 1845. The impressive north ridge was first climbed by Captain John Percy Farrar (a future President of the Alpine Club) and Wylie Lloyd with guide Josef Pollinger of St. Niklaus in the canton Valais on 18 August 1893.

Ascents are usually made from the Rifugio Ottorino Mezzalama (3,036 m), the Monte Rosa hut (2,795 m); if traversing the peaks via Pollux's north ridge, PD+, the Capanna Quintino Sella (3,585 m), and the Cesare Volante e Giorgio Rossi bivouac hut (3,850 m).

Castor and Pollux

In Greek and Roman mythology, Castor and Pollux or Polydeuces were twin brothers, together known as the Dioskouri. Their mother was Leda, but Castor was the mortal son of Tyndareus, the king of Sparta, and Pollux the divine son of Zeus, who raped Leda in the guise of a swan. Though accounts of their birth are varied, they are sometimes said to have been born from an egg, along with their twin sisters and half-sisters Helen of Troy and Clytemnestra.

In Latin the twins are also known as the Gemini or Castores. When Castor was killed, Pollux asked Zeus to let him share his own immortality with his twin to keep them together, and they were transformed into the constellation Gemini. The pair were regarded as the patrons of sailors, to whom they appeared as St. Elmo's fire, and were also associated with horsemanship.

They are sometimes called the Tyndaridae or Tyndarids, later seen as a reference to their father and stepfather Tyndareus.

Birth and functions

The best-known story of the twins' birth is that Zeus disguised himself as a swan and seduced Leda. Thus Leda's children are frequently said to have hatched from two eggs that she then produced. The Dioscuri can be recognized in vase-paintings by the skull-cap they wear, the pilos, which was explained in antiquity as the remnants of the egg. Whether the children are thus mortal or half-immortal is not consistent among accounts, nor is whether the twins hatched together from one egg. In some accounts, only Pollux was fathered by Zeus, while Leda and her husband Tyndareus conceived Castor. This explains why they were granted an alternate immortality. It is a common belief that one would live among the gods, while the other was among the dead. The figure of Tyndareus may have entered their tradition to explain their archaic name Tindaridai in Spartan inscriptions or in literature Tyndaridai, in turn occasioning incompatible accounts of their parentage.
