Bollettino dell'Osservatorio della Regia Università di Torino, 1877 (vol. 12)
This 1877 volume from the Turin university observatory's bulletin, issued by the Osservatorio astronomico di Torino for scholars of astronomy and meteorology, presents monthly meteorological records as printed diagrams. The four pictures are daily charts for July, April and December 1877, each plotting barometric pressure, thermometer readings, vapour tension and relative humidity as hand-ruled wavy traces on squared grids with Italian labels and day numbers along the axes. A designer might take the dense, rhythmic line work and the squared graph paper structure as a source for abstract patterns, data-visualisation textures or vintage scientific layouts.
