Compendia and pocket instruments
Compendium and astronomical or pocket instruments are different names for an instrument that combines several individual tools in miniature form. A compendium is usually rectangular but can also have any other shape; it always opens and has several "shelves" between the lid and the base. All of these levels have individual functions - there may be sun dials, moon dials, star dials, astrolabes, conversion charts, maps, calendars or other data needed for the operation of the instrument. A well equipped compendium may also have extra parts that can be fitted for a particular function; they could be a vane, a attachable plum line or rulers. Schissler is known to have created compendia with additional shelves to put in. As the time and effort involved in producing such a compendium was considerable, they were usually reserved for wealthy travellers or even made to order for members of royal houses. It was usually tailor-made to the traveller’s wishes as the compendium’s functions were intended to determine local time in foreign countries and convert it into the time at home or conduct other studies. The compendium was also meant to show the wealth, the open mind and the fine education of its owner. Due to their scale and multifunctionality, however, the compendia could not be used for scientific purposes because the data they provided was usually not precise enough. The possible variety of instruments in a compendium though was limitless.
