Legba is one of the most widely recognized of the loas. In Haiti Papa Legba is the intermediary between the loa and humanity. He stands at a spiritual crossroads and gives (or denies) permission to speak with the spirits of Guinee. The center post in all hounfors (Voodoo temples) are called poteau Legba. Through this post the loa enter the ceremonies, and it's also where there food is placed. Dancing, drumming, possession, and all the activities of ceremony revolve around the poteau Legba. He is always the first and last spirit invoked in any ceremony because he is able to translate the requests of humans into the languages of the spirits and loas.
In Haiti, Attibon Legba is an old man who walks with a twisted cane, smokes a pipe, wears a straw hat, and carries a macoutte (straw sack); Avradra Legba is said to be a wandering vagabond. (In the Yoruba diaspora, Ellegua is mostly associated with Papa Legba since both share the role of being the god of the crossroads. In contrast to Papa Legba, however, Eleggua is a trickster child.)
Because of his position as 'gate-keeper' between the worlds of the living and the spirits, Legba is generally identified with Saint Peter who holds a similar position in Catholic tradition. But he is also depicted in Haiti as St. Lazarus, or St. Anthony. (Notes compiled by Gethin James)
