Jump To ECM Entry Online Commentary Introduction
GC: A strong core of A-related witnesses for a is accompanied by several incoherencies. The b attestation is coherent only if IR is set to b or, with IR=?, if connectivity is set to 10, which is adequate given the eye-catching change of tense.
TP: The incoherencies in the a attestation can easily be explained by adaptation to the preceding aorist. In fact, the tense change is noticeable. It may be motivated by a wish (of the author or of an editor) to bring in a durative aspect, fitting the following present participle. The incoherencies in the a attestation, however, show a clear tendency to parallelize rather than to change the tense. In conclusion, the superior quality of the A-related core in the a attestation is outweighed by TP in favor of b.
