Sonnenuhr vor der Herzog August Bibliothek

Nestled in the picturesque town of Wolfenbüttel in Lower Saxony, Germany, the sundial in front of the Herzog August Library is a hidden gem that combines historical significance, scientific ingenuity, and artistic beauty. This late Baroque masterpiece, crafted from sandstone, features twelve timepieces and serves as a fascinating tribute to the art of timekeeping and the rich history of the region.

The Historical Journey of the Sundial

The sundial's story begins in 1738 when it was designed by Johann Friedrich Penther, a mathematician and architectural historian. Penther created this intricate timepiece at the behest of Count Christian Ernst zu Stolberg-Wernigerode for the pleasure garden in Wernigerode. Originally referred to as a solar compass or gnomonic attachment, the sundial was erected on August 3, 1738, in front of the pleasure palace in the garden.

In 1790, the sundial was acquired by Baron von Münchhausen from Hedwigsburg, where it was placed in the courtyard of the now-destroyed Hedwigsburg Castle. The sundial found its way to the Herzog August Library in 1956, thanks to a generous gift from the estate owners. Extensive restoration work was carried out, and in 1968, the sundial was installed at its current location on Lessingplatz, dedicated to the philosopher and astronomer Giordano Bruno.

The Artistic Design

The sundial is a testament to Baroque artistry and stands on a three-tiered sandstone pedestal, which is segmented by profiled, segmental steps. The structure is divided into three main parts: the base, the middle section, and the roof adorned with a fruit bowl.

The square, profiled base is connected to the middle section by elaborate ornamental work. The middle section is decorated with four large outer shells of scallops, while the transitions at the corners are embellished with acanthus leaves. The roof, placed atop the middle section, features garlands and profiles, with the inner sides of the scallops serving as additional sundials. The entire sundial is crowned by a fruit basket, a replica created in 1992 by the stonemasonry center in Königslutter, as no historical references for the original basket were available.

The Twelve Timepieces

The sundial boasts twelve timepieces, each with its unique design and function. Four of the time indicators are located on the pedestal, made from bluish hard stone, with two having been renewed due to wear. The remaining eight timepieces are distributed across the middle section and the roof, with the scallop shells housing both outer and inner sundials. The time indicators on the scallops are crafted from various metallic materials, and the hour markers are engraved into the sandstone and inlaid with gold leaf.

Johann Friedrich Penther, the designer of the sundial, published a textbook in 1733 titled Gnomonica Fundamentalis, which included 15 copper engravings on the construction of sundials. The twelve timepieces on this sundial feature different shadow indicators, aligned parallel to the Earth's axis. These timepieces display the true solar time for Wolfenbüttel, known as true local time. The hour markers on the various dials can be read, with the time indications varying by up to 32 minutes from Central European Time, depending on the season and astronomical conditions.
