Reading edition
It is not clear what the word glés, gléssib, which occurs frequently in the following passage, means. In mod. Irish, gléas, in one meaning, is a means or instrument for doing a thing. The verb gléasaim="to harness." It seems to have some such meaning here. The winds were apparently harnessed, curbed, or fettered two and two, the whole being held together in one fetter. In another sense gléas means "harmony."
