Tutor, writer, translator, and cartographer, Giovanni Gallucci studied in Padua and moved to Venice, where he spent the rest of his life. The range of his activity embraces both scientific and humanistic fields.
In his most important work, Theatrum Mundi et Temporis (Theater of the world and time; Venice, 1588), Gallucci presents a general treatment of celestial phenomena, including both astronomical and astrological aspects. He declares the definite intention to clear his discussion of any trace of superstition in order to avoid a conflict with the Catholic Church, which some years before had condemned astrology.
The most noticeable peculiarity of Gallucci’s book is given by the 48 maps of Ptolemaic constellations. The maps are represented in trapezoidal projection, and show the brightest stars of each asterism and the corresponding mythological figure. The stars’ positions are drawn from Nicolaus Copernicus ’ De Revolutionibus Orbium Coelestium. The set of maps of Theatrum renders this work one of the first celestial atlases of the modern age.
