Pisanki are intricately decorated Easter eggs which have been part of the Slavic tradition for centuries. The oldest example of a pisanka in the Polish region was found in Ostrówek and is believed to be 900 years old. Even prior to the arrival of Christianity, the egg had long been a symbol of fertility and spring, which brings new life into the world. In the context of Christianity, the Easter egg became synonymous with the hope and faith in Jesus Christ through his resurrection.
Pisanki are decorated through different means, and various techniques have been employed throughout the Slavic tradition. The oldest examples had been covered in wax which was then carved to create a design, and later dipped in a dye made from onion peels. Different modes of decoration have yielded a variety of Easter egg art. Beets, flower petals, oak bark, and rye are employed to create colors when making kraszanki. Drapanki are decorated through careful etching into the the surface of a dyed egg shell, and pisanki are artfully hand-painted into various Slavic motifs. Creating naklejanki involves gluing scraps of paper, flower petals, and other decorative materials to the eggshell, while oklejanki are adorned with bulrush pith or yarn. Probably the most intricate and time-consuming are pisanki ażurowe, or wydmuszki. Raw eggs are emptied of their contents through a carefully created opening, while preserving the shape of the egg. The shell is then decorated by drilling very small holes in the surface to create a lace-like look.
In the past pisanki were strictly a tradition cultivated by women, and men were not allowed inside the house during the process as it was believed they had the power to cast a spell on the eggs and cause bad luck.
