Shalom Rene,
     Comet Hale Bopp generally is looked at as the "Cousin" comet of Hyakatake.
     That is because, one year to the day....April 11, l996, and 1997...these two comets crossed paths at nearly the same spot in the heavens.  And both of the April 11th. dates were related to Passover.   One may have been Purim, which is a shadow of the Exodus....when an enemy of Israel was concentrating on their annialation.
 
Shalom,
Miriam Brown
