The maintenance of the bulwarks of the city in proper order was naturally a matter of supreme importance, and although the task was sometimes neglected when no enemy threatened, it was, on the whole, attended to with the promptitude and fidelity which so vital a concern demanded. There was little occasion for repairs, it is true, on account of injuries sustained in the shock of war, for until the invention of gunpowder the engines employed in battering the walls were either not powerful enough, or could not be planted sufficiently near the fortifications, to produce much effect. Most of the damage done to the walls was due to the action of the weather, and, above all, to the violent and frequent earthquakes which shook Constantinople in the course of the Middle Ages. The charge of keeping the fortifications in repair was given to special officers, known under the titles, Domestic of the Walls (ὁ Δομέστικος τῶν Τειχέων),[392] Governor of the Wall (Ἄρχων τοῦ Τείχους),[393] Count of the Walls (Κόμης τῶν Τειχέων).[394] (1) The earliest record of repairs is, probably, the Latin inscription on the lintel of the inner gateway of the Porta of the Pempton. It reads: PORTARUM VALID † DO FIRMAVIT LIMINE MUROS PUSAEUS MAGNO NON MINOR ANTHEMIO. The age of the inscription cannot be precisely determined, but the employment of Latin, the Gothic form of the D in the word _valido_, the allusion to Anthemius, and the situation of the legend upon the Inner Wall, taken together, point to an early date. [Illustration: Inscriptions on the Gate of Rhegium.] From the statement of the inscription it would seem that soon after the erection of the wall by Anthemius, either this gate or all the gates in the line of the new fortifications had to be strengthened. The only Pusæus known in history who could have presumed to compare himself with Anthemius was consul in 467, in the reign of Leo I.[395] There may, however, have been an earlier personage of that name. (2) A considerable portion of the Inner Wall (τὰ ἔσω τείχη) was injured by an earthquake in 578, the fourth year of the reign of Zeno;[396] but no record of the repairs executed in consequence of the disaster has been preserved.
