What is in this image? Describe it as if you were explaining it to someone from the 15th century.

Ye are beholding an image depicted with the art of drawing, showing a woman garbed in simple clothes akin to a scholar or an apothecary, with a small badge hanging from her neck and a pouch strapped over her shoulder. ''Tis clear that she practices some manner of healing or study. She is attending to a young child sitting on a bench, who clutcheth a toy beast, perhaps a dragon or fantastical creature, in his hands whilst the woman examines his head with a small tool very much like a miniature painter’s brush or a quill.In the background there exists a strange chart hanging upon the wall, adorned with letters listed in a descending size. This chart mayhaps serves a purpose of testing or enhancing vision, akin to a magnifying glass or reading stone, showing letters clear and less clear to discern from a distance. This setting could well be an apothecary’s chamber or a scholar''s study, dedicated to the well-being and learning of bodily humors and sight. Such a portrayal is as intriguing as it is wondrous, revealing the practices of care and study from an age far ahead of our own times.
