He says: “I heard the avalanches falling every five minutes nearly—as if God was pelting the Devil down from Heaven with snowballs. From where we stood, on the Wengern Alp, we had all these in view on one side: on the other, the clouds rose from the opposite valley, curling up perpendicular precipices like the foam of the Ocean of Hell during a Springtide—it was white and sulphury and immeasurably deep in appearance.” From the summit they “looked down upon a boiling sea of cloud, dashing against the crags on which we stood.”

The avalanches and sulphurous clouds of course became part of the décor of “Manfred:”

“Ye avalanches, whom a breath draws down

In mountainous overwhelming, come and crush me!
