Still the most careful accounts were found to conflict on many points, and neither Porter nor his successors had removed the discrepancies and contradictions that had been so long remarked.

The first to make the attempt was a Mr. Ellis, but his negatives were entirely destroyed in the course of the rough journey to the sea. At lentgth Herr Stolze made another and very successful effort.[1] He was attached to a German scientific expedition, sent out to the East in 1874, under the direction of Dr. Andreas, to observe the transit of Venus. Stolze spent some time travelling over Persia and visited among other places Persepolis and Fasa in the winter of 1874; but his real work began in June 1878, a season of the year when the heat is excessive, and when the process of developing the negatives within a closed box involved actual suffering.

He found vertical sun of summer better suited for photographing the inscriptions than the bas-reliefs, especially those situated in the deep shade of the doorways.
