See Salmon, Hist. Intr. to New Test., p. 23Of.; also Milligan, Expos. Bib., Rev., p. 235; and Plummer, Pulp. Com., Rev., p. 337. Farrar's interpretation (following Reuss, Hitzig, and others) is Neron Kesar, using Hebrew letters in the spelling and omitting most of the vowels, as follows (see Early Days of Christianity, p. 540), viz:—
N=50
R=200
O=6
N=50
N(E)RON=306
K=100
S=60
R=200
K(E)S(A)R=360
This interpretation is the one now generally accepted by the advanced school of commentators in the present day. On the other hand if the last letter of the name (N) be dropped we have the value of 616, which is the alternate reading in some manuscripts. Moulton, however, says the number contains “probably a temporary allusion of which the point is now lost” that gave a clue to the general significance, viz. “world-religion and superstition in contradistinction to world-force.” (Mod. Read. Bib., Rev., p. 209). “The non-identification of Nero with the 666 by any early writer is significant.” (Cowan, art. “Nero”, Hastings' Dict. of Bib.). “Surely not ‘Nero Kaisar,’ but ‘Ashhur-Ramman’!” Cheyne, Fresh Voyages on Unfrequented Waters, p. 171—1914).
