5,2:2 Ad Horrea

Ad Horrea, a station situated on the eastern coastal artery of Roman Africa, has been unaccountably shifted away into a sub-network. The clue to this error is the set of connecting lines around it. They form an absurd Y shape which was not in the TP author's repertoire of valid links, and give us confidence that shifting Ad Horrea (named for its grain store) and the stations near it as an entire group leads to the correct solution. The site of Cubin has never been found, possibly because this error misled archaeological researchers as to where they should look. This emendation proposes that Ad Horrea is part of the main highway and the Cubin, is in fact a place in the hinterland, not a highway station. The manuscript appears to have shifted an entire assembly of line-work out the correct plane, an interestingly complex case of strike slip.
