The Medieval Pelican
The pelican of the Middle Ages was thought to pierce herself in her breast in order to feed her blood to her young. Alternate stories tell of how the pelican would kill her young in a fit of pique, and then pierce her breast in later remorse. The blood thus brought forth, falling on the dead chicks, brought them back to life.
Generally, depictions of the pelican are meant to indicate Christ the Saviour who shed his blood in a like manner.
In medieval heraldry, a pelican is an eagle-beaked bird always shown plucking at her breast. If shown alone she is blazoned (described in heraldic terms) as "vulning herself". If the young are shown with the parent, she is blazoned as "a pelican in her piety".
The Catholic Encyclopedia
The Pelican is a symbol of the atonement and the Redeemer. It was supposed to wound itself in order to feed its young with its blood and to bring to life those who were dead -- the "pelicane who stricketh blood out of its owne bodye to do others good" (Lyly, Euphues). Allusion is made to this belief in "Hamlet" (act iv): --
To his good friend thus wide I'll ope my arms And, like the kind, life-rendering pelican, Repast them with my blood.
Therefore it was deemed a fitting symbol of the Saviour, the nostro pelicano of Dante, Who shed His blood in order to give eternal life to the children of men. Skelton in his "Armorie of Birds" says: --
Then sayd the Pellycan:
When my Byrdts be slayne
With my bloude I them revyve.
Scripture doth record
The same dyd our Lord
And rose from deth to lyve.
The Book of Beasts, a twelfth-century bestiary
The Pelican is excessively devoted to its children. But when these have been born and begin to grow up, they flap their parents in the face with their wings, and the parents, striking back, kill them. Three days afterward the mother pierces her breast, opens her side, and lays herself across her young pouring out her blood over the dead bodies. This brings them to life again.
In the same way, Our Lord Jesus Christ, who is the originator and maker of all created things begets us and calls us into being out of nothing. We, on the contrary, strike him in the face. As the prophet Isaiah says: "I have borne children and exalted them and truly they have scorned me." We have struck him in the face by devoting ourselves to the creation rather than the creator.
That was why he ascended into the height of the cross, and, his side having been pierced, there came from it blood and water for our salvation and eternal life.'
Of the pelican
'I am like pelican of the wilderness' (Psalms, 102:6). The pelican is a bird of Egypt, living in the wilderness of the River Nile, from which it gets its name. For Egypt is known as Canopos.
It is devoted to its young. When it gives birth and the young begin to grow, they strike their parents in the face. But their parents, striking back, kill them. On the third day, however, the mother-bird, with a blow to her flank, opens up her side and lies on her young and lets her blood pour over the bodies of the dead, and so raises them from the dead.
In a mystic sense, the pelican signifies Christ; Egypt, the world. The pelican lives in solitude, as Christ alone condescended to be born of a virgin without intercourse with a man. It is solitary, because it is free from sin, as also is the life of Christ. It kills its young with its beak as preaching the word of God converts the unbelievers. It weeps ceaselessly for its young, as Christ wept with pity when he raised Lazarus. Thus after three days, it revives its young with its blood, as Christ saves us, whom he has redeemed with his own blood.
In a moral sense, we can understand by the pelican not the righteous man, but anyone who distances himself far from carnal desire. By Egypt is meant our life, shrouded in the darkness of ignorance. For Egiptus can be translated as 'darkness'. In Egypt, therefore, we make a wilderness (see Joel, 3:19), when we are far from the preoccupations and desires of this world. Thus the righteous man creates solitude for himself in the city, when he keeps himself free from sin, as far as human frailty allows.
The pelican kills its young with its beak because the righteous man considers and rejects his sinful thoughts and deeds out of his own mouth, saying: 'I said, I will confess my transgressions unto the Lord, and thou forgavest the iniquity of my sin' (Psalms, 32:5). It weeps for its young for three days: this teaches us that whatever we have done wrong by thought, word or deed, is expunged by tears. It revives its young by sprinkling them with its blood, as when we concern ourselves less with matters of flesh and blood and concentrate on spiritual acts, by conducting ourselves virtuously. It is also a characteristic of this bird, they say, that it always suffers from thinness, and that whatever it swallows, it digests immediately, because its stomach has no separate pocket in which to retain food. Food does not fatten its body, therefore, but only sustains it and gives it strength. Indeed, the life of a hermit is modelled on the pelican, in that he lives on bread but does not seek to fill his stomach; he does not live to eat but eats to live.
