The Balluderon Stone, otherwise known as Martin's Stone is a class II Pictish cross slab in situ at Balluderon, Angus.
A slab of Old Red Sandstone, the cross slab is situated in a field and protected by iron fencing. The slab, of which only the lower half remains, bears the remnants of a Celtic cross, two mounted riders, a serpent and z-rod symbol and a Pictish beast design. Local tradition associates the slab with the Legend of the Nine Maidens who were devoured by a dragon which was subsequently slain by a hero named Martin. Folk etymology names this as the origin of Strathmartine, the valley in which the slab stands.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
