And, besides, it suits divine studies not to be heavy with wine. “For unmixed wine is far from compelling a man to be wise, much less temperate,” according to the comic poet. But towards evening, about supper-time, wine may be used, when we are no longer engaged in more serious readings. Then also the air becomes colder than it is during the day; so that the failing natural warmth requires to be nourished by the introduction of heat. But even then it must only be a little wine that is to be used; for we must not go on to intemperate potations. Those who are already advanced in life may partake more hilariously of the bowl, to warm by the harmless medicine of the vine the chill of age, which the decay of time has produced. For old men’s passions are not, for the most part, stirred to such agitation as to drive them to the shipwreck of drunkenness. For being moored by reason and time, as by anchors, they stand with greater ease the storm of passions which rushes down from intemperance. They also may be permitted to indulge in pleasantry at feasts. But to them also let the limit of their potations be the point up to which they keep their reason unwavering, their memory active, and their body unmoved and unshaken by wine. People in such a state are called by those who are skilful in these matters, acrothorakes.[470] It is well, therefore, to leave off betimes, for fear of tripping. One Artorius, in his book _On Long Life_ (for so I remember), thinks that drink should be taken only till the food be moistened, that we may attain to a longer life. It is fitting, then, that some apply wine by way of physic, for the sake of health alone, and others for purposes of relaxation and enjoyment. For first wine makes the man who has drunk it more benignant than before, more agreeable to his boon companions, kinder to his domestics, and more pleasant to his friends. But when intoxicated, he becomes violent instead. For wine being warm, and having sweet juices when duly mixed, dissolves the foul excrementitious matters by its warmth, and mixes the acrid and base humours with agreeable scents. It has therefore been well said, “A joy of the soul and heart was wine created from the beginning, when drunk in moderate sufficiency.”[471] And it is best to mix the wine with as much water as possible, and not to have recourse to it as to water, and so get enervated to drunkenness, and not pour it in as water from love of wine. For both are works of God; and so the mixture of both, of water and of wine, conduces together to health, because life consists of what is necessary and of what is useful. With water, then, which is the necessary of life, and to be used in abundance, there is also to be mixed the useful.
