Seneca · On gathering ideas
Letters 84.3
We should follow, men say, the example of the bees, who flit about and cull the flowers that are suitable for producing honey, and then arrange and assort in their cells all that they have brought in; these bees, as our Vergil says,
pack close the flowing honey, And swell their cells with nectar sweet.
Seneca, Letters to Lucilius 84.3, translated by Richard Mott Gummere
