Easter Egg Symbolism

Various Easter celebrations and fun activities revolve around eggs. Ancient people must have been amazed to see a new living creature emerge from a seemingly dead object. In ancient Persia, people gave eggs to each other at the spring equinox, and they set that date as the beginning of a new year. Easter egg symbolism arose much later as Christians used eggs to represent the rock tomb and the hatching chick as a symbol of Christ emerging from the tomb.

Lent was instituted to remember the fasting of Jesus, and people who were fasting would not eat meat from cows, sheep, pigs, or fowl. It was also common practice to avoid eating eggs, but chickens still laid eggs, so people decorated them. The original egg decorations were just plain vegetable dyes, but crimson eggs emerged in honor of the blood of Christ.

Eastern European people used intricate designs on eggs called pysanky, which they sold in Ukrainian shops. In Germany, people pierced and hollowed eggs and hung them on shrubs and trees like Christmas trees. In some countries, people used eggs in games. In addition to egg hunts, egg rolling activities were also conducted on the White House lawn. Some egg rollings were started at Sunday School picnics and parades before the Civil War.

The shell of a hen’s egg weighs only about one-fifth of an ounce, and it’s made from calcium carbonate just over one-hundredth of an inch thick. Despite the thin shell, chicken eggs can withstand 130 pounds of force. If it is set perfectly still with its pointed end up, an egg is almost impossible to break with one hand. Only an uneven force, like hitting it on something, can crack an eggshell.

Easter egg symbolism can remind us of Christ’s resurrection, but the egg’s design is one more example of the wisdom God has built into everything we see in the creation.

Egg Shape and the “Egg-quation”

When you look at the eggs of different birds, you will notice that they have different shapes. Some are round like the eggs of most owls, and some are elliptical like the eggs of an emu. Others are oval, such as chicken eggs, or pear-shaped like the eggs of a penguin. Why is egg shape important? There has been a need to know how to pack eggs to support them to prevent cracking. This is not just important for people who raise chickens and sell eggs at your local grocery store but also for conservationists protecting birds in the wild.

This need to understand egg shapes led to studies by scientists at Kent University in England. They came up with a mathematical formula with four essential inputs: 1-egg length, 2-maximum breadth, 3-diameter where the pointed end terminates, and 4-location of the egg’s maximum diameter in relation to the midpoint of its length. The problem was that the earlier mathematical analysis didn’t work on pear-shaped eggs, but the formula works for any egg shape by adding the fourth variable.

This is a classic example of two things. One is that research that may seem pointless to a casual observer frequently provides needed information. So, for example, people wanting to transport eggs, incubate eggs efficiently, and restore bird populations in areas where they have become extinct will use this equation.

A second thing this research shows is the incredible design of the egg. An engineering equation allows the design of precise egg shape construction to fit all environments. This is a complex engineering problem with practical applications, and it shows that even the ordinary egg speaks of the Creator’s wisdom and skill in providing for His creatures.

Mother Birds Sing to their Eggs

Recent studies have shown that mother birds sing to their eggs while incubating them. Researchers found that bird embryos learn to identify the sounds of their species before they hatch from the eggs. They also found that the singing is deliberate and serves a purpose.

The reason mother birds sing to their eggs can’t be for their survival, because singing puts the mothers at risk from predators. Then what is the advantage of the singing? In addition to learning the songs of their species, the young birds learn to recognize unfamiliar songs produced by other bird species. The mother’s singing also affects the heart rate of the unhatched bird. All of the eggs in the study of unhatched baby birds showed a decrease in the babies’ heart rate when their mothers sang to them.

Previous research has shown that the heart rate of unborn humans also slows when the mother is in a stable situation and increases when the mother is under stress. Similarly, the researchers speculate that the singing of the mother bird aids the survival of the chick. The research co-author said, “Birds are like humans in that there is a mother- or father-offspring communication even before birth.”

The message is clear that the individual begins life and learning before being put into the world of self-preservation and survival. Mother birds sing to their eggs, and human mothers sing and talk to their babies before birth. In both cases, the offspring benefit. Whether a bird or a human, individual existence begins when life begins–not when the egg hatches or the baby is born.
