The cappella dei Mercanti, Negozianti e Banchieri ('chapel of merchants, shopkeepers, and bankers') is a Catholic chapel in the historic city center of Turin.
The chapel, whose construction was authorized during the 16th century, was built at the end of the 1600s and most of the artwork it contains originated in the 1600 and 1700s, in the baroque style.
The walls of the chapel present numerous seventeenth-century paintings, all inspired by the theme of the Biblical Magi. The altar dates back to 1797 and is the work of Michele Emanuele Buscaglione. On either side there are two reliquaries, while on the wall there are three paintings by the Jesuit painter Andrea Pozzo. The baroque frescoed ceiling by Legnanino depicts Heaven, prophets, sibyls and biblical episodes and dates to 1694-1695. The organ on the wall opposite the altar dates back to the eighteenth century.
The sacristy contains several sacred objects, but above all the famous Perpetual Calendar by Giovanni Plana, one of the oldest calculator machines (it is equipped with rotating drums and a transmission system that allows the correct combination of the various information contained in the system) which allows precise calendrical calculation over a period of 4000 years starting from year zero (including the calculation of lunations, days of the week and Christian holidays).
References:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
