In Ezekiel i. 6–11, the four living creatures have each four wings, as also in x. 21 according to the Hebrew.  But in the latter passage, according to the Vatican text of the Septuagint, each has eight wings, as Codd. R. and Casaub. read here.  Cyril seems to have confused the number in Ezekiel with that in Is. vi. 2:  each one had six wings.  By “a wheel of four sides” Cyril explains Ez. i. 16:  a wheel in the midst of a wheel, as meaning two circles set at right angles to each other, like the equator and meridian on a globe.
