- Astrological observations, or doctrines drawn from the late circle about the sun : or brief observations, from the late halos circle that encompassed the body of the sun, on Wednesday the 15. of May 1672. in form of a rainbow, and continued (from the beginning to the end) for the space of near four hours, to the great amazement of hundreds of spectators in London, and several other parts. From which remarkable and unusual apparition (together with other coelestial apperances) may rationally be conjectured, that considerable vengance is approaching towards the enemies of Great Brittain, the heavens no way favouring their present designs now on foot against His Majesty and loyal subjects.
