Lupus 5

This constellation seems to have been an unidentified animal for both the Greeks and Romans, simply known as Therion. Both cultures thought Centaurus was offering this animal as a sacrifice. By the time Johann Bayer published his catalogue of constellations in the early seventeenth century, the animal was considered a wolf.
Lupus or the wolf. Filomeleo son of Demeter and Yasonte was the first agriculturist of the world according to Greek mythology. It seems to be that his Licaón grandfathers invited to Zeus to a banquet and he served to him to his own Arcade grandson like food. Zeus recomposed theA body of this one and he turned it star, Arcturus (a Bootis); but according to another version after recomposing the body of Arcade occurred it to raise to a goatherd and punished to the grandfathers turning it a wolf or Lupus and setting afire its mansion.

Lupus, is precious austral constellation that crosses the parallel of 40º of South latitude. One is in a rich zone in stars since it is practically in the equator of the Milky Route, therefore we can observe great amount of stellar and globular clusters. He is visible in the South hemisphere during the months of February to October and in the North hemisphere it culminates to very little distance of the observable horizon during the month of June, is easy to identify it if we left from Scorpius and we observed the Eastern zone of the same one.

Lupus limits the north with the constellations from Scorpius and Libra to the east with Centaurus, the south with Circinus and the west with the constellations of Norma and Scorpius again.

Lupus I located the 2 to it of May of 1986 at the age of 19 years from the locality of Cán Picafort, Majorca, Spain, logically, where I write these lines to you from the parallel +40º of North latitude Lupus it culminates to few degrees of the horizon and is observable the North zone of the constellation; I hope in future trips to be able to contemplate it completely.
