Oct 13 -Miracle of the sun
REV 8 -1 And when he had opened the seventh seal, there was silence in heaven, as it were for 1/2 hour.
(38 yrs btwn Knock /Fatima).
I believe the Apocalyptic Marian apparitions are the 7 Thunders of REV 10 (1) GUADALUPE -(2) GOOD SUCCESS 1594- (3) LASALETTE (4) LOURDES 1858 (5) KNOCK (6) FATIMA (7) AKITA, were the 7 Thunders in REV 10
Fatima punctuates the 7 Thunders bc although there were 6 visits over 6 mos to the children there were 2 dates in Aug, making a total 7 thunders. When the Children were detained AUG 13 the people who did show up reported the thunder.
Also note John/James were called the sons of Thunder and Jesus gave Mary to John at the cross. James saw the fist apparition (bi Location) of Mary and John the Last in REV 11:19 "...the ARK of his testament was seen in his temple, and there were lightnings, and voices, and an earthquake, and great hail."
