OIHB meaning in General ?

The Old Icelandic Homily Book (Stock. Perg. 4to no. 15), also known as the Stockholm Homily Book, is one of two main collections of Old West Norse sermons; the other being the Old Norwegian Homily Book (AM 619 4to), with which it shares eleven texts. Written in around 1200, and both based on earlier exemplars, together they represent some of the oldest examples of Old West Norse prose.

The Old Icelandic Homily Book (OIHB) contains 62 texts and parts of texts, 50 of which are homilies. For this reason it is better considered a homiletic hand-book rather than a homiliary. Further, the ‘homilies’ it contains, as with most Old Norse homilies, conform more closely to the definition of sermons. The other texts are wide-ranging and include excerpts from Stephanus saga, a translation of part of pseudo-Ambrose’s Acta Sancti Sebastiani, and a fragment of a text dealing with musical theory, amongst others.
