Wel wist he why, and what therof he mente;

For with that faire cheyne of love he bond

The fyr, the watir, the eyr, and eek the lond

In certeyn boundes, that they may not flee.

(Knightes Tale, p. 92.)

That þe world with stable feith / varieth acordable chaungynges // þat the contraryos qualite of elementȝ holden amonge hem self aliaunce perdurable / þat phebus the sonne with his goldene chariet / bryngeth forth the rosene day / þat the mone hath commaundement ouer the nyhtes // whiche nyhtes hesperus the eue sterre hat[h] browt // þat þe se gredy to flowen constreyneth with a certeyn ende hise floodes / so þat it is nat l[e]ueful to strechche hise brode termes or bowndes vp-on the erthes // þat is to seyn to couere alle the erthe // Al this a-cordaunce of thinges is bownden with looue / þat gouerneth erthe and see / and [he] hath also commaundementȝ to the heuenes / and yif this looue slakede the brydelis / alle thinges þat now louen hem to-gederes / wolden maken a batayle contynuely and stryuen to fordoon the fasoun of this worlde / the which they now leden in acordable feith by fayre moeuynges // this looue halt to-gideres poeples / ioygned with an hooly bond / and knytteth sacrement of maryages of chaste looues // And loue enditeth lawes to trewe felawes // O weleful weere mankynde / yif thilke loue þat gouerneth heuene gouerned yowre corages /.

(Chaucer’s Boethius, bk. ii. met. 8.)
