Now the author of the Vita Tertia and Probus undertook the same problem of working these incidents into the main thread of the Muirchu story, and they solved it in different ways. Probus solved it by a single interpolation, grouping all the new matter together and finding a place for it before the sojourn with Germanus. In the Vita Tertia there are three distinct interpolations arranged as follows:—

(Muirchu) Reads with Germanus.

(Interp.) Sojourns with Martin.

(Muirchu) Germanus sends Segitius with him to Rome.

(Interp.) Visits a hermit in quodam loco and receives staff of Jesus.

(Muirchu) Is ordained bishop by Amator.

(Interp.) Visits Rome, and goes thence ad montem Arnon when he salutes the Lord.

It is difficult to say which of the arrangements is the more unskilful. The same matter is found in a more expanded and “advanced” form in the Tripartite Life, where the arrangement is as follows (Rolls ed. p. 25 sqq.):—

(1) Patrick reads with Germanus; (2) is tonsured by Martin; (3) visits a cave, in the Tyrrhenian sea, “between mountain and sea,” where there were three other Patricks, and a beast infested a fountain; (4) Victor bids him go to Ireland, and Germanus sends Segitius with him; (5) Patrick goes to sea, with nine, and visits an island, where he found a young married couple who had lived there since the time of Christ; and (6) goes thence to Mount Hermon, near the island, where the Lord gives him the staff of Jesus and grants him three requests; (7) goes to Rome.

In these three documents we have the same matter differently combined, variously modified and augmented. Probus presents it in a more advanced stage than the Vita Tertia, the Tripartite in a more advanced stage than Probus. The matter, however, is not homogeneous. The visit to Pope Celestine at Rome has no legendary superstructure, and is found in the W document (V₂ and V₄) which does not contain any of the other incidents. The rest of the common material depends on three motives: (1) the association of Patrick with Martin; (2) the staff of Jesus; (3) converse with the Lord. The Vita Tertia presents these motives in their simplest form: (1) it is not stated that Patrick was tonsured by Martin; (2) the staff of Jesus is received from a hermit, not from the Lord; (3) there is no account of the conversation, we are simply told salutavit Dominum ut Moyses. The Tripartite Life brings the second and third motives into the same setting.
