* According to [http://www.ascension-research.org/davidson.html "A Dictionary of Angels: Including the Fallen Angels"](ISBN-13: 978-0029070529), Castiel is an Angel Of Thursday in the occult lore. This may be a reference to the fact that Supernatural aired on Thursday nights on The CW when the character was introduced. Crowley refers to Cas as "The Angel of Thursday" in [[6.20 The Man Who Would Be King]]. He also comments that it isn't Castiel's day; this may refer to the show having been moved to Fridays.
* There is a municipality in Switzerland called Castiel. Its coat of arms is Saint George killing a dragon. It looks similar to Michael fighting a dragon. This image has appeared in paintings in [[2.13 Houses of the Holy]] and [[4.22 Lucifer Rising]].
