Siluan (Serbian Cyrillic: Силуан; fl. 14th century) was a Serbian Orthodox monk and poet who lived and worked in the Hilandar monastery at Mount Athos in the 14th century. Very little is known about him. The mystical tradition of prayer known as hesychasm left a strong imprint in Serbian medieval literature and art, which is evident already in the works of Domentijan and Teodosije the Hilandarian, but most prominently in the writings of archbishop Danilo II, patriarch Jefrem, monk Isaija and Siluan. Siluan is the author of hymns to Saint Sava and St. Simeon (Stefan Nemanja). History knows of two Serbian monks called Siluan active on Athos, living two centuries apart, but researchers have been inclined to credit the 14th century Siluan with the authorship of Verses for St. Simeon and Verses
