In it he narrates his personal experiences with many great [[ ascetic]] s whom he met during his extensive travels, and repeats the edifying stories which these ascetics related to him . Though the work is devoid of critical discrimination and teems with miracles and ecstatic visions, it gives a clear insight into the practices of Eastern monasticism, contains important data on the religious cult and ceremonies of the time, and acquaints us with the numerous heresies that threatened to disrupt the Church in the East.
It was first edited by [[Fronton du Duc]] in ''Auctarium biblioth. patrum,'' II (Paris, 1624), 1057-1159.

A Latin translation, by [[Ambrose Traversari]], is printed in Migne, ''[[Patrologia Latina]]'', LXXIV, 121-240, and an Italian version made from the Latin of Traversari (Venice, 1475; Vicenzo, 1479).
