The vital numerals were defaced, but there seemed no doubt that the last fragment was a part of S (6000) and as the writer states that there was only room for one more letter, SΔ or 6004 (495) is the only year that will fit the fourth indiction. “The architect Bubroff is about to show that the church was built in the fifth century.” [335] A book on mechanics (περὶ παραδόξων μηχανημάτων) has been ascribed to Anthemius.

They were drawn so by Dr. Covel about 1675, they appear so in the careful engraving in Miss Pardoe’s _Bosphorus_, and these are fully confirmed by Strzygowski and Forchheimer, _Die Wasserbehälter von Konstantinopel_, pp. 12 and 71. The use of the pointed arch in the east is probably an unbroken tradition from early days in Egypt. [342] _Die Wasserbehälter_, p. 130, &c. [343] 1799, p. 236. [344] _Journal of Roy. Inst. Brit.

Lukium--unslaked lime, burnt brick (both in a fine powder), cotton wool very fine pulled and strewed on, linseed oil. Cistern plaister--Lime, burnt brick, cotton or flax, water [use] almost dry, smooth it and saturate with oil. [350] _Blasii Caryophili opusculum de antiquis marmoribus_, 1743.
