Maximinus Daza died

Maximinus' death was variously ascribed "to despair, to poison, and to the divine justice". Based on descriptions of his death given by Eusebius, and Lactantius, as well as the appearance of Graves' ophthalmopathy in a Tetrarchic statue bust from Anthribis in Egypt, sometimes attributed to Maximinus, endocrinologist Peter D. Papapetrou has advanced a theory that Maximinus may have died from severe thyrotoxicosis due to Graves' disease.
