Me and my wife visited sicily in may 2017. we were in agrigento on the south coast of sicily, when we sat at a terrace in the city center. as always, i look up frequently. i've spotted quite some objects in the last years flying around, so i guess i'm always hoping to catch something. when i looked up at the sky, i noticed something white in the distance, that seemd to move from right to left. it went very slow, at a floating pace. more people noticed it, and started filminh it. it seemed to shapeshift while moving, and my best guess is, it looked like an angel with distinctive wings. it moved very slowly, and turned around while moving through the sky. it didn't make any sound and it changed shapes. it was solid, but it was expending and contracting. it was actually really beautiful to see. eventually it disappered behind the builings. i know it moved by itself. it wasn't blown by the wind, and it weren't balloons because they stayed at the same altitude all the time. balloons would go up.
