The _Turks_ look upon Earthquakes as Ominous, as the vulgar do upon Eclipses, not understanding the Philosophy of them. During my stay in _Constantinople_, which was above 2 Years, there hapned but one, which was _October 26. 1669._ about six a Clock in the Morning a stark Calm preceeding. It lasted very near a Minute, and we at _Pera_ and _Galata_ were as sensible of it, as those who were on the other side of the Water; but praised be God nothing fell, and we were soon rid of the Fears in which this frightful Accident had cast us, being in our Beds, and not able by reason of the Surprize in so little a space to have past through a Gallery down a pair of Stairs into the Court, if we had attempted it. The _Turks_ made direful Reflexions on it, as if some Calamity would inevitably fall upon the Empire, quickly forgetting the great Triumphings and Rejoycings which they exprest but a few Days before for the Surrendry of _Candia_. In the Year 1668. in _August_, the Earth shook more or less for forty-seven Days together in the lesser _Asia_ at _Anguri_ (_Ancyra_), and for fifteen at _Bacbasar_, as we heard from a _Scotch_ Merchant, who liv'd there: And particularly, that at this latter Place on the second of _August_, between three and four of the Clock in the Afternoon it lasted for a quarter of an Hour; several Houses were overthrown, and some hundreds of Chimneys fell (it being a very populous Town) and yet there were but seven kill'd. The trembling being so violent, both _Turks_ and _Christians_ forsook their Houses, and betook themselves to the Fields, Vineyards, and Gardens, where they made their Abode for several Days.
