Moon suffered eclipse, but she emerged from the Earth’s shadow about a quarter of an hour before she rose at Jerusalem (6 h. 36 m. p.m.): the penumbra continued upon her disc for an hour afterwards. Speaking of the Emperor Claudius, Dion Cassius[63] says:—“There was going to be an eclipse on his birthday. Claudius feared some disturbance, as there had been other prodigies, so he put forth a public notice, not only that the obscuration would take place and about the time and magnitude of it, but also about the causes which produce such events.” This is an interesting statement, especially in view of what I have said on a previous page about the indifference of the Romans to Astronomy. It would, likewise, be interesting to know how Claudius acquired his knowledge, and who coached him up in the matter. This eclipse occurred on August 1, A.D. 45. Barely half the Sun’s diameter was covered. Philostratus[64] states that “about this time while he was pursuing his studies in Greece such an omen was observable in the heavens. A crown resembling Iris surrounded the disc of the Sun and darkened its rays.” “About this time” is to be understood as referring to some date shortly preceding the death of the Emperor Domitian which occurred on September 18, A.D. 96. This has usually been regarded as the earliest allusion to what we now call the Sun’s “Corona”; or, as an alternative idea, that the allusion is simply to an annular eclipse of the Sun. But both these theories have been called in question; by Johnston because he cannot find an eclipse which in his view of things will respond as regards date to the statement of Philostratus, and by Lynn on the same ground and on other grounds, _more suo_. The question of identification requires looking into more fully. There was a total eclipse on May 21, A.D. 95, but it was only visible as a partial eclipse in Western Asia and not visible at all in Greece. This is given as the conclusion arrived at by the German astronomer Ginzel. But it does not seem to me sufficient to overthrow, without further investigation, the fairly plain language of Philostratus, which is possibly confirmed by a passage in Plutarch[65] in which he discusses certain eclipse phenomena in the light of a recent eclipse. The date of Plutarch’s “recent” eclipse is somewhat uncertain, but that fact does not necessarily militate against his testimony respecting the Corona or what is regarded to have been such. The statement of Philostratus, treated as a mention of a total solar eclipse, is accepted as sufficiently conclusive by Sir W. Huggins and the late Professor R. Grant. Johnston, to meet the supposed difficulty of finding an eclipse to accord with the assertion of the historian, suggests that “perhaps some peculiar solar halo or mock Sun, or other meteorological formation” is referred to. But Stockwell has advanced very good reasons for the opinion that the eclipse of Sept. 3, A.D. 118, fully meets the circumstances of the case.
