The suggestion in my own mind

The suggestion in my own mind is that they were not mirages from terrestrial primaries, or they would not be so confined to one period, but were shadows or mirages from something that was in temporary suspension over the Baltic and Sweden…

Not mirages from terrestrial primaries

Fort mentions that on Oct. 8, 1888, at Merexull, Russia, a mirage of a city, identified as St. Petersburg, 200 miles away, was seen, lasting an hour.

On Oct. 16, 1884, at Lindsberg, Sweden, a mirage of a large town was seen, with four-storied houses, a castle and a lake.

Through lenses rimmed with horizons

On Oct. 10, 1881, in Rugenwalde, Pomerania, the mirage of a village was seen, complete with snow-covered, icicle-adorned¬†roofs and distinctly visible human forms. Fort notes, “It was believed that the mirage was a representation of the town of Nexo, on the island of Bornholm…about 100 miles northwest…”.

Mirage of an unknown city

June, 1801–a mirage of an unknown city, seen for more than an hour, at Youghal, Co. Cork, Ireland. It was a representation of mansions, Fort says, surrounded by shrubbery and white palings, with forests behind. In October 1796, a mirage of a walled town had been seen distinctly for half an hour at the same town. The next year, in March, a walled town was also seen in Youghal.
