Another important group of poets at this time were the Cavalier poets. The Cavalier poets wrote in a lighter, more elegant and artificial style than the Metaphysical poets. They were an important group of writers, who came from the classes that supported King Charles I during the Wars of the Three Kingdoms (1639–51). (King Charles reigned from 1625 and was executed 1649). Leading members of the group include Ben Jonson , Richard Lovelace , Robert Herrick , Edmund Waller , Thomas Carew , Sir John Suckling , and John Denham . The Cavalier poets can be seen as the forerunners of the major poets of the Augustan era , who admired them greatly. They "were not a formal group, but all were influenced" by Ben Jonson .  Most of the Cavalier poets were courtiers , with notable exceptions. For example, Robert Herrick was not a courtier, but his style marks him as a Cavalier poet. Cavalier works make use of allegory and classical allusions, and are influence by Latin authors Horace , Cicero , and Ovid . 
Guðmundur Kamban (1888-1945) wrote Vi mordere in 1920: Guðmundur wrote the fictional work in Danish but the play came out in an Icelandic version in 1969, called Vér morðingjar (that is, We Murderers).
The National Theatre 1950
When the National Theatre was established in 1950, Icelanders came into possession of a professional theatre house. The Reykjavík Theatre Company (that is, “Leikfélag Reykjavíkur) had, since 1897, operated at a building called Iðnó. With the establishment of the National Theatre it was thought that the activity of the Reykjavík Theatre Company would fall away, but that was not the experience, rather the existence of two professional theatres. With that, Icelandic theatrical life came into bloom and Icelandic playwriting began to thrive. During the 1960s, 13 new Icelandic plays were premiered.
Most Productive Playwrights
Amongst the most productive playwrights is Jónas Árnason (1923-1998). His plays include musicals with his brother, the musician Jón Múli (1921-2002), which have enjoyed great popularity.
Jökull Jakobsson (1933-1978) was the most productive playwright of the first years of the professional theatre. At the same time, he wrote many interesting radio plays. One of his plays, Hart í bak (1962), was performed more than 200 times.
Ólafur Haukur Símonarson (b. 1947) is the most productive playwright of recent years. He writes realistic plays in which he tries to shed light on the lives of ordinary people.
Heaney is an Irish poet who is influenced by R. S. Thomas and Ted Hughes. Like them, he writes of the countryside and of the natural world in his early poems. His later poems move from private history to the public events of the past and how they have influenced the present political and military situation in Northern Ireland. Heaney is attempting to go beyond the daily events of the life around him and to discover the forces below his country’s history that can bring back life and hope. He received the Noble Prize for literature in 1995.
