What does Holmes' phrase omne ignotum por magnifico mean?

Holmes' phrase "omne ignotum pro magnifico" translates to "everything unknown is taken to be magnificent." It suggests that people often perceive the unknown or unfamiliar as grand or impressive, attributing positive qualities to it simply due to its mystery. This reflects a tendency to romanticize or idealize what we do not understand. In the context of Holmes' work, it highlights the allure of the unknown and the human inclination to imagine possibilities beyond our current knowledge.
