Two Israeli aglyphous colubrid snakes seem to mimic venomous viperid snakes. Spalerosophis diadema cliffordi resembles sympatric desert viperids, especially Vipera persica fieldi, in girth, coloration and defensive behaviour. Coluber ravergieri nummifer resembles the sympatric Vipera palaestinae in length, coloration and defensive behaviour. Direct evidence of functional mimicry is absent, except that man is frequently misled. Because several conventional conditions are fulfilled, these appear to be two cases of Batesian mimicry. Any of five hypotheses may enable the evolution of such mimicry systems in which the model may be lethal. Some individuals of both mimic species greatly increase the morphological resemblance to the models by behaviourally flattening and triangulating the head in the defensive display. This behaviour is distinct from that of flattening the head as part of a general flattening of the body, to increase the area shown an enemy or in basking. Parallely, cobras are mimicked by colubrids which erect the neck and spread a hood. Both this and the head-triangulation behaviours may have evolved from the generalized body-flattening response. This may have its origin in the thermoregulatory (basking) flattening common to snakes and lizards.

The critique of Francis Thomson constitutes only part of Ostrowski’s book. The other part, completely unrelated to the first one, is dedicated to a comparison of the intellectual development of the two halves of the Christian world in the Middle Ages. Ostrowski’s assertion that the Byzantines did not include logic in their school curriculum is untrue. What seems to him to be the main difference between East and West does not take root until the end of the 12th century. The West was drifting away from the common patterns of ancient Mediterranean civilization. The East largely remained the same. The Byzantines did not feel any special inclination toward the practical application of theoretical ideas. The people of Old Rus’, on the contrary, were quick at learning and innovating. Respect for tradition inevitably played a smaller role in a nascent culture than in a culture that had been born old.
