A lot of those discoveries couldn’t be proven for many years after the deaths of their authors. So it was hard to tell how significant they were. A lot of the things that Galileo said couldn’t be proven either. In fact some were outright wrong and some could be directly disproven based what was know at the time (e.g. reconciling the size and distance of stars). So either they couldn’t tell anyone because nobody would believe them, they weren’t sure about how significant it was or maybe it was just irrelevant at the time (e.g. the Ancient Greek steam engine)
