If you look at the two charts in the link,one is Valens chart by him,the other by a modern astrologer.
The main difference is that the map ruler,Mercury is in diferente signs.It is unlikely Valens would calculate his aC ruler wrongly.Might he be using sideral zodiac? At the time the diferences in zodiacs were small of course

update: one of the comments says he used the vernal point at 8 aries not at 0?
