On most seals, the 'sakelle' (from Latin sacella = purse) refers to the imperial treasury, but this example belongs to a cleric: he identifies himself as a deacon and he bears the dignity of kouboukleisios, which tells us he was a chamberlain of the patriarch. We can thus conclude that he was probably attached to the patriarchal treasury as first chartoularios, an office hitherto unknown on seals. The patriarchal sakelle, on the other hand, is mentioned on another 11th century seal in the Dumbarton Oaks Collection (DO Seals V, 42.24: Nicholas, diakonos of Hagia Sophia, kouboukleisios and epi tes patriarchikes sakelles)
