Crown of sonnets

A crown of sonnets or sonnet corona is a sequence of fourteen sonnets, usually addressed to one person, and/or concerned with a single theme. Each of the sonnets explores one aspect of the theme, and is linked to the preceding and succeeding sonnets by repeating the final line of the preceding sonnet as its first line. The first line of the first sonnet is repeated as the final line of the final sonnet, thereby bringing the sequence to a close.

An advanced form of crown of sonnets is also called a sonnet redoublé or heroic crown, comprising fifteen sonnets, in which the sonnets are linked as described above, but the final binding sonnet is made up of all the first lines of the preceding fourteen, in order. The fifteenth sonnet is called the Mastersonnet.
