Question

When has the frost wrought silence?

Answer 1

This inactiveness is mostly experienced during the winter season because the frost outside covers everything which is possible and takes grip and conquers over man's energy. So, it implies the winter season when it is told that "when the frost wrought a silence".

Answer 2

Answer:

It’s easy to see why the seasons are popular with poets. Each has its own distinct character; their temperatures and weather conditions are partly predictable, but can still be wildly irregular; they are a central to the earthly cycle of death and regrowth. The seasons can seriously affect our mood, and they can also be physically dangerous, with their extremes of heat and cold. As with our recent Stars challenge, it almost seems like the seasons were designed as metaphors for poetry!
