How deeply have you researched his methodology in ascribing historical dates back to, say, Solomon’s completion of the First Temple, or from thence back to the end of Noah’s Flood, to form your opinion of James Ussher’s grasp of historical events?

Ussher chose October 23rd for his moment of Creation as, under the old calendar, it was the autumn equinox, a traditional start to the year. He believed the 23rd would have been a Sunday, as time would surely have begun on the first day of the week, and he specified the previous evening, as traditionally this was when each day began.How an archbishop calculated the Creation
