Annals of medical history . species come through a densemedium, the greater [relatively] appearthe objects. Thus in the same mass ofwater, objects at the bottom are relativelymore enlarged than those at the Soij one looks through two lenses (specillaocularia) placed one injront of the other, allobjects look much larger and nearer. In thesame way there are certain stars which,when near the horizon appear larger andnearer, but when towards the zenith (inmedio cell) seem smaller and more species near the horizon come througha greater depth of medium, and they comethrough more of the atmosphere which isloaded with the multitude of vapors thatare ever about the earth than do speciesfrom the region of the zenith (e medioceli). . Let efgh be the earth and abcdthe sphere of vapors around it. Let bebe the horizon. Then a star near thehorizon will be seen along the line be,one at the zenith along ae. But be is 48 This property of water was, of course, wellknown to the ancients and is mentioned among. greater than ae and therefore the speciesin that region have to pass through morevapors. For thesame reason, allstars as theyrise northwardappear less tous [, in Italy]and as theypass eastgreater; thenas they sink southward they are yetgreater and returning on the east lessagain. For with us [in Italy] a star is nearthe horizon when it turns southward andit passes eastward near the zenith. Let abcd be the earth and fa ourhorizon, efgh the sphere of vapors,kl the equator k and e a northernand f a southernstar. But thesouthern star isnear our horizonand is seen alongthe line fa, thenorthern star is,however, nearerthe zenith and seen along the line ea,which is less than fa. For a similar reason some of theplanets seem larger when they are inquadrature to the sun, so that his speciesis refracted through a greater part oftheir sphere, a matter of which we shalltreat presently. But (not only the character but) alsothe position of the medium affects theappearance o
