The Sons of the Dragon (Gyldayn)
The Sons of the Dragon is a history of Aenys I Targaryen and Maegor I Targaryen. It was written by Archmaester Gyldayn of the Citadel of Oldtown. It uses Grand Maester Gawen as a source. A revised version of The Sons of the Dragon was included as a chapter of Gyldayn's history of the Targaryens, Fire & Blood, but the ending of this version provides textual evidence that it was written as a separate, stand-alone work before this.
