Genesis 8:5

(P). the tenth month Another date is here given. The tops of other mountains were visible on the 1st day of the 10th month. Reckoning 30 days for a month, we thus have an interval of 73 days between the grounding of the ark upon the mountains of Ararat and the visibility of the other mountains.

tops of the mountains This detail in the narrative suggests that Ararat was thought to be a lonely peak towering above all the neighbouring mountains.
