Revelation 17:9-10
9 “This calls for a mind with wisdom. The seven heads are seven hills on which the woman sits. 10 They are also seven kings. Five have fallen, one is, the other has not yet come; but when he does come, he must remain for only a little while.

History

1-Julius
2-Augustus
3-Tiberius
4-Caligula
5-Claudius
6-Nero

Could it just be a coincidence?
