In ictu oculi

One source is from the Bible, in 1 Corinthians 15:52: "In momento, in ictu oculi, in novissima tuba", translated in the KJV as "In a moment, in the twinkling of an eye, at the last trump:"[1] where the Latin is itself a translation of the original Koine Greek phrase ἐν ῥιπῇ ὀφθαλμοῦ (en rhipēi ophthalmou).

[6][7] More than the original context of the phrase itself, the Latin may be better known as the title of a painting by Juan de Valdés Leal (4 May 1622 – 1690).

[11][12] A volume of Rubens' designs for Antwerp's triumphal arches for the 1634 reception of the new Spanish governor, Cardinal-Infante Ferdinand, stands as a symbol of political disillusionment.

[13] The other painting of the pair is Finis Gloriae Mundi, "End of worldly glory," which depicts a dead bishop and a knight.
