From my experience in 2006 with the first Icon I studied my teacher had an extensive library. One of her books: Ethiopia:Illuminated Manuscripts, from the UNESCO World Art series 1961, inspired this 'Annunciation'. You can see the Byzantine influence as Our Lady is holding the spindle of wool, the symbol read as 'she who spun God in her womb'.
Here we have Archangel Gabriel with the message:
Have no fear
God is with you
