The Prose Edda 2.53

"How are the uninvolved terms of poesy made? By calling each thing by its proper name. What are the simple terms for poesy? It is called Poetry, Glorifying, Song, Laud, and Praise. Bragi the Old sang this, when he was travelling through a forest late at evening: a troll woman hailed him in verse, asking who passed:

'Trolls do call me Moon's . . . . . . of the giant, Storm-sun's (?) bale, Fellow-in-misery of the sibyl, Warder of the circled ring-earth, Wheel-devourer of the heaven. What is the troll but that?' He answered thus:

'Skalds do call me Vidurr's Shape-Smith, Gautr's Gift-Finder, Bard not faulty, Yggr's Ale-Bearer, Song's Arrayer, Skilled Smith of Verse: What is the Skald but this?'

And as Kormákr sang:

I make more Glorifying By far o'er Hákon's great son: I pay him the song-atonement Of the gods. In his wain Thor sitteth.

And as Thórdr Kolbeinsson sang:

The Shield-Maple let many swift ships And merchant-craft, and speedy War-boats o'er the sea pour; The skald's ready Song of Laud waxed.

Laud, as Úlfr Uggason sang:

Now the stream to the sea cometh; But first the Laud I sang forth Of the Messenger of Sword-Rain: Thus I raise the praise of warriors.

Here poesy is called praise also.
