German Indologist Hermann Jacobi dated Lalitaditya's invasion of Kannauj to 14 August 733 CE, a date that was accepted by several later historians. This theory is based on the "Gaudavaho", a text composed by Yashovarman's court poet Vakpati. This text describes a solar eclipse (an inauspicious omen), which Jacobi considers to be an allusion to Yashovarman's defeat. Jacobi also bases his conclusion on a subsequent verse, which he translates as ""The corner of his eye-brow became twisted on account of the shaking of his [kingly position."" Assuming 733 CE as the date of Lalitaditya's victory, Goetz dated the beginning of the conflict to 730 CE or earlier.
