What are historical examples of (alleged) miracles that were attested to by two or more (self-proclaimed) eyewitnesses?

The resurrection of Jesus is the most famous and obvious one, with the apostles being the eyewitnesses. Latter-day Saints would probably put forth the (https://en.wikipedia.org/wiki/Three_Witnesses) & (https://en.wikipedia.org/wiki/Eight_Witnesses) witnesses to the miraculous golden plates. Are there any other notable examples in the history of the Church? **Note**: Why two or more witnesses? Because *in the mouth of two or three witnesses shall every matter be established* (2 Cor 13:1).
