Community and kinship
The synaxarion records that Anubius lived with a small group of monks in concord so complete that they were of one mind and one soul. Several accounts name among his brethren Poemen the Great, the celebrated abba of the Egyptian desert; the Wikipedia tradition counts Anubius as one of a set of blood-brothers that included Poemen, with Anubius the eldest in years and Poemen the elder in monastic authority.
A saying attributed to Poemen describes their shared life: they lived together in complete unity and unbroken peace until death broke up their association. This portrait of unbroken peace among the brethren is the feature for which Anubius is chiefly remembered.
