Leo 1st decan
0° - 10°·Subruled by Leo
First decan of Leo (0°–10°). Subruled by Leo - the pure expression of the sign's archetype.
Traditional reading
The Sun subrules its own territory in the first decan of Leo under the modern triplicity system, making degrees 0 to 10 the sign's archetypal core. Astrological writers render this band as fixed fire at full brightness: self-assurance that assumes an audience, generosity performed on a grand scale, and creative drive centered on personal expression. Standard descriptions include a natural theatricality in speech and gesture, pride that is wounded by indifference more than by opposition, and warmth that organizes social gatherings around itself the way the Sun organizes its planets. Steadiness distinguishes these portraits from Aries fire; the flame here is a hearth, not a spark.
Chaldean face tables assign the opening decan of Leo to Saturn, the sequence's most dramatic reversal, setting the greater malefic over the Sun's own threshold. Medieval sources attached images of severity and struggle to this face, and traditional commentators sometimes read it as authority tested by burden. The contrast between the two schemes underlines the decans' status as minor dignity; Hellenistic astrologers inherited them from Egyptian star calendars and never fully reconciled the competing rulership systems.

Reference, not advice
This is cultural and astronomical reference, not personal prediction or advice.
The triplicity decan system assigns each decan a subruler from the sign's element triplicity, in zodiacal order. This is the modern Western convention; classical Hellenistic decan assignments (Chaldean order) differ. See methodology.
