Depends on what you mean by 'revered'. That's one of the problems importing a post-Christian mindset into polytheism. Most belief systems did not have a notion of piety such as we have, which involves a reverencing a deity with love and faith, which is returned by that deity toward the worshiper. So in Egyptian practice for example, there were many deities with temples whose priesthood's job was to continually pray spells of impotence and defeat against that deity so that it would not be able to harm the populace. In that case, piety was continuing offering up curses against the deity. In Sparta, the patrons of the city were Apollo and Athena. They dealt with the problem of Ares by building a temple to him, then binding his idol in chains. The idea was very similar, a chained Ares would lack the power to aid the enemies of Sparta in battle. But this sort of worship doesn't look like reverence like we think of it. It's a sort of deep respect sure, but it's not what we might be first thinking of when we think of having deep respect for something. It's more like the deep respect you might have for a bottle of nitroglycerin, biohazardous sharps, or radioactive waste.
