I owe many of the above details to a sketch of Cecco’s life in a Florentine MS. which I judge from the handwriting to be of the seventeenth century, and of which the anonymous author appears to be well informed; also, to a MS. copy of the elaborate sentence, much more full than the fragments given by Lami and Cantù.

The superstitions concerning comets scarce come within our present scope. They will be found ably discussed by Andrew D. White in the Papers of the American Historical Association, 1887. We are told by a contemporary that Henry IV. lost his life in 1610 through neglect of the warning sent him by the learned Doctor Geronymo Oller, priest and astrologer of Barcelona, based upon the portents of a comet which appeared in 1607.—(Guadalajara y Xavierr, Expulsion de los Moriscos, Pampeluna, 1613, fol. 107).
