Engraving of an early azimuth compass
Azimuth compass. Engraved illustration of an early design of azimuth compass. This is designed to tell the angle between magnetic north and the Suns position. The glass hemidome above the compass rose allows the inclusion of a vertical needle. This casts a shadow onto the rose from the Sun. At higher latitudes this can be used to determine the local magnetic variation (difference between true and magnetic north). This illustration was first published in the Gentlemans Magazine in 1754

EDITORS COMMENTS
This print showcases an exquisite engraving of an early azimuth compass, a remarkable instrument that revolutionized marine navigation in the 18th century. The intricate illustration depicts a design specifically created to determine the angle between magnetic north and the position of the Sun. At its center lies a compass rose, surrounded by a glass hemidome that houses a vertical needle. As sunlight filters through this dome, it casts a shadow onto the rose, revealing vital information about local magnetic variation. Published in 1754 within the esteemed Gentlemen's Magazine, this monochrome masterpiece captures both scientific precision and artistic elegance. The fine engravings expertly depict every detail of this navigational marvel, showcasing its square shape adorned with delicate markings and inscriptions. Transporting us back to an era when maritime exploration was at its peak, this print invites contemplation on how determination and calculation were intertwined with adventure and discovery. It serves as a testament to human ingenuity and our relentless pursuit of knowledge. Todd-White Art Photography has skillfully captured not only the essence of this historical artifact but also its significance in shaping our understanding of navigation during that time period. This photograph is more than just an image; it is a window into history itself – reminding us of humanity's ceaseless quest for exploration and innovation.
