Father Solines's visions came from Revelations, chapter four, verse six to ten.
"Also in front of the throne there was what looked like a sea of glass, clear as crystal. Surrounding the throne on each of its sides, were four living creatures covered with eyes in front and behind. The first one looked like a lion; the second looked like a bull; the third had a face like a human face; and the fourth looked like an eagle in flight. Each one of the four living creatures had six wings, and they were covered with eyes, inside and out. Day and night they never stop singing:
"'Holy, holy, holy is the God almighty, who was, who is, and who is to come.'
"The four living creatures sing songs of glory and honor and thanks to the one who sits on the throne, who lives forever and ever. When they do so, the twenty-four elders fall down before the one who sits on the throne, and worship him who lives forever and ever."
The exact quote is from my "Good News Bible", which is not in the old dialect.
Solinas quotes Robert Louis Stevenson.
"Happy hearts and happy faces
"Happy play in grassy places
"That was how in ancient ages
"Children grew to kings and sages."
