Refractio solis inoccidui in septemtrionalibus oris iussu serenissimi ac potentissimi principis Caroli Undecimi .. circa solstitium aestivum 1695 aliquot observationibus astronomicis detecta : = Midnats solens raetta och synlige rum uti Norrlanden ...
A 1695 Latin and Swedish astronomical treatise by Johann Billberg, printed at the Stockholm press of B. Nic. Wankijf and written to record observations of the midnight sun in northern Sweden, made at the command of King Charles XI. The pictures are letterpress and woodcut-style material: a decorated initial A, a black-letter title line with royal titles, a carved acanthus and shell ornament, and a plain geometric diagram of a circle with lettered points and intersecting lines. A designer could draw on the ornate initial and the stylized foliage ornament for period display type, borders and dividers, and on the diagram for clean scientific line work.
