What is "kalfsvisa"

The Kálfsvísa ("Kálfr's vísa", Kálfr being maybe the name of its author), sometimes mistakenly called Alsvinnsmál, is a poem partially preserved in Snorri Sturluson’s Skáldskaparmál.

Its three stanzas in fornyrðislag mostly consist of a þula of horses and their riders, Norse heroes (for instance Grani and Sigurðr). The Kálfsvísa also includes a narrative dealing with the Battle on the Ice of Lake Vänern between Áli and Aðils.
