Struck By Blindness

Percusserunt caecitate... Quoddam genus caecitatis est quod Graece aorasia dicitur, id est, avidentia, qua quaedam videntur, quaedam non videntur. Sodomitae ergo alia videbant, sed ostium Lot videre non poterant. Moraliter Lot justos significat. Sodomitae invidos et detractores designant, qui quoddamodo ostium quaerunt per quod ad Lot irrumpant, quando homines bona facta reprehendere volunt, sed non possunt invenire aditum reprehendendi, quia illo virtutis claustro munito corruptores mentium nihil habent quod reprehendant. Remigius Antissiodorensis, Commentarius In Genesim, Cap XIX Source: Migne PL 131.91c

They struck them with blindness... 1 There is a certain type of blindness which in Greek is named aorasia, that is, inobservance, in which certain things do appear, but others do not. Therefore to the Sodomites some things appeared, but they were not able to find the door to Lot. Morally Lot signifies the righteous man and the Sodomites designate envious men and detractors, who seek the door that they may burst in on Lot, when they wish to denounce a man for good deeds, but they are not able to find way to reprehend because with him concealed by the guard of virtue the corrupt of mind have nothing to denounce. Remigius of Auxerre, Commentary On Genesis, Chap 19 1 Gen 18.11
