Omar Khayyam, the astronomer-poet of Persia, who wrote about eight hundred years ago, gave open expression to the same liberal-minded views, urging tolerance and freedom for all religious creeds and classes.
The last murderous mob attack led by Moullas against the Babis occurred at Yezd in April, 1891.

It was probably an outcome of the Babi massacre which had taken place at Isfahan the previous year, and which, owing to the fiercely hostile attitude of the priests, was allowed to pass unnoticed by any strong public condemnation.

On that occasion a party of the sect, pursued by an excited and blood-thirsty mob, claimed the 'sanctuary' of foreign protection in the office of the Indo-European Telegraph Company, and found asylum there.

Negotiations were opened with the Governor of the town, who arranged for a safe conduct to their homes under military escort.

Trusting to this, the refugees quitted the telegraph-office, but had not proceeded far before they were beset by a furious crowd, and as the escort offered no effectual resistance, the unfortunates were murdered in an atrociously cruel manner.
