The Escorial Taktikon (other spellings: Escurial Taktikon, Escorial Tacticon, Escurial Tacticon), also known as the Taktikon Oikonomides after Nicolas Oikonomides who first edited it, is a list of Byzantine offices, dignities, and titles composed in Constantinople during the 970s (971–975 or 975–979).[1][2][3] The list contains, among many entries, the commanders (strategoi) of the Byzantine Empire's eastern frontier during the Byzantine-Arab Wars,[4] as well as a series of judicial offices.[5]
