You're welcome. Usually, the easiest answer is the reason. Hundreds/thousands of years after the fact, it is sometimes difficult to ascertain what the simple explanation might have been at the time.

That's why I love history, and the history of technology. There are frequently links exposed that require a wider knowledge. For example, the fermented honey drink, mead, persisted in popularity for several centuries in Catholic countries after the Reformation vis a vis the Protestant countries. Why? The Catholic Church burned many more candles (eschewed by the Protestants), and accepted tithings in the form of wax from the poor. Poor peasants would get their wax by searching for beehives in the wild. What to do with all the leftover honey? Mead.

It is a little tough to figure it out without the wider historical context.
