1206 A. D. On the last day of February, there was, ac- 

 cording to Joaquin de Villalba (Epidemiologia espanola, 

 Madr. 1803, torn. i. p. 30), complete darkness for six 

 hours, turning the day into night. This phenomenon 

 was succeeded by long-continued and abundant rains. 

 " El dia ultimo del mes de Febrero hubo un eclipse de 

 Sol que duro seis horas con tanto obscuridad como si 

 fuera media noche. Siguieron a este fenomeno abun- 

 dantes y continuas lluvias." A very similar phenomenon 

 is recorded for June, 1191, by Schnurrer, th. i. pp. 

 258, 265. 



1241 A.D. Five months after the Mongolian battle at 

 Liegnitz, the Sun was darkened (in some places ?) and

 quently the days preceding, and immediately succeeding 

 the battle of Miihlbach, in which the Elector John 

 Frederick was taken prisoner. Kepler says in Para- 

 lipom. ad Vitellium, quibus Astronomice pars Optica 

 traditur, 1604, p. 259, "The elder and younger Gemma 

 record that in the year 1547, before the battle between 

 Charles V and the Duke of Saxony, the Sun appeared 

 for three days as if it were suffused by blood, while at 

 the same time many stars were visible at noon." " Re-
