The Astronomicum Caesareum is a beautifully crafted astrolabe manual, to be used in order to calculate planetary alignment and the location of the stars. Petrus Apianus, a German court astronomer for Emperor Charles V dedicated the work to his patron. In return the emperor promoted Apianus to court mathematician and made him an imperial knight.
Seed pearls sewn into the pages, moving pieces, and dozens of drawings and diagrams make the manuscript a masterpiece. Apianus provided new commentary on Halley’s Comet (seen in 1531 and shown in the last image) and called for instruments to be used in astronomy rather than outdated calculation tables. Only 40 known copies remain in the world.
Mallow Castle is a 33-acre site composed of gardens and parkland on which three buildings sit: the remains of a 16th-century fortified house (pictured above), a 19th-century mansion to the north, and the ruins of a 13th-century castle to the east. The fortified house is a long rectangular three-storey building, with two polygonal towers on the north-west and south-west corners. It is early Jacobean in style, featuring high gables, stepped battlements, and mullioned windows. The wings of the house project from the center of the south and north walls, with the entrance in the north wing. The design of the house was to provide a field of fire around it entirely.
The 16th-century fortified house is believed to have been built by Sir Thomas Norreys before his death in 1599. Following his death, his niece Elizabeth and her husband Sir John Jephson inherited the house, with their family remaining in Mallow for almost 400 years. It was placed under siege by Richard Butler, Lord Mountgarret, in 1642 during the Irish Confederate Wars and did not fall. It was captured in 1645 by James Tuchet, Lord Castlehaven. The house was badly damaged by fire during the Williamite War and subsequently abandoned by the Jephsons. The Jephsons built the new mansion house on the site of the older castle’s stable block.
