The writing of akathists (occasionally spelled "acathist") developed within the Slavic traditions as a genre of its own as part of the general composition of an akolouthia, although not all compositions are widely known nor translated beyond the original language. Reader Isaac E. Lambertsen has done a large amount of translation work, including many different akathists. Most of the newer akathists are pastiche, that is, a generic form imitating the original 6th-century akathist to the Theotokos into which a particular saint's name is inserted. In the Greek, Arabic, and Russian Old Rite traditions, the only akathist permitted in formal liturgical use is the original akathist.
