La meridiana del tempio di S. Petronio : tirata, e preparata per le osseruazioni astronomiche l'anno 1655 : riuista, e restaurata l'anno 1695
This is a 1695 Bologna publication by astronomer Giovanni Domenico Cassini, recording his meridian line set into the church of San Petronio for astronomical observations, printed for a learned audience of astronomers. The pictures are fine engraved ornaments, a rosette and scrolled cartouche, plus architectural plans and a long floor-plan showing the meridian's course through the nave, useful to designers for historic baroque ornament and measured drawings.
