Does anybody know what Ptuj was called before it was renamed Colonia Ulpia Traiana Poetovio in 103. The only information I could find was on Wikipedia-

Ptuj is the oldest city in Slovenia. It dates back to the Stone Age and was settled by Celts by the Late Iron Age.[2] By the 1st century BC, the settlement was controlled by Ancient Rome. In 69 AD, Vespasian was elected Roman Emperor by his legions in Ptuj, and the first written mention of the town of Ptuj is from the same year. The city of Poetovio was the base-camp of Legio XIII Gemina in Pannonia. The name originated in the times of Emperor Trajan, who granted the settlement city status and named it Colonia Ulpia Traiana Poetovio in 103. The city had 40,000 inhabitants until it was plundered by the Huns in 450.[2]
