The three ages of man (woman) is a fairly popular theme in fine art.
I will post a couple of examples from art of the past. Then some photos for inspiration on the theme.
For Practical art
, try any of these:
1. You may like to concentrate on one age group for your painting.
2. You may feel ambitious and try your hand at all 3 ages in a painting or drawing.
3. You may like to copy the Klimt or Giorgione works.
Looking forward to seeing the art!!
Also, if you come across artwork on the web on the theme... please post links.
