Lectures differ from trainings in that they are shorter, usually an evening or as a brief comment during a Sunday service. I have lectured in Chartres for the week-long programs sponsored by Veriditas (Grace Cathedral, San Francisco) and for school groups. Twice I have spoken to middle school students, followed by actually making a labyrinth together. Mostly, lectures are scheduled in conjunction with a visit for on-site consulting or installation, or on the evening before a two-day intensive training. My fee for a lecture ranges from $150 to $500 depending on the situation (plus travel expenses).
