He probably set out from Prague sometime between 1170 and 1180, and was certainly in Jerusalem prior to 1187, since he describes it as being under the control of the Latin Kingdom of Jerusalem.
Podemos pensar que saíu de Praga nalgún momento entre 1170 e 1180, e estivo con certeza en Xerusalén antes de 1187, xa que a describiu baixo o Reino de Xerusalén.
